Two mistakes: we were maintaining two redundant caches for
findAssignedGlobals, and callings tryToParse before checking globalsCache,
when often globalsCache already had a stored result.
This speeds up both getPrelinkedOutput (because we don't spend any time
generating the identity source map) and toStringWithSourceMap (because we
don't have to combine those source maps).
We still generate line number comments for files without source maps, so
it's relatively easy to find the source line for a stack trace.
An example of an npm package that triggers this bug is the `cli-color`
package, which has a package.json file with a "main" property whose value
is "lib", and a "lib" directory that contains an index.js file.
This is critical because it means Resolver objects can now survive
development server restarts, which means the optimistic Resolver#resolve
method can remember results indefinitely. Thanks to this change, the
Resolver#resolve method has practically disappeared from rebuild
performance profiles.
We try to kill any mongod processes before starting new ones, but this
change kills it when the development server shuts down, too.
Killing mongo on shutdown is particularly important for tests that run
meteor multiple times in a row, and for whatever reason fail to find and
kill running mongod processes on startup, e.g. because the --port has
changed (#7563).
This comment by @glasser seems to suggest this is a reasonable idea:

I originally added the exception-caching functionality in order to avoid
calling files.stat repeatedly for files known to be missing, but now that
we're using statOrNull, knowledge of missing files (as indicated by
statOrNull returning null) is being properly cached.
The reason it's dangerous to cache exceptions is that (for example) when
an ENOENT exception indicates the file is missing, there will be no more
change events for that file, effectively making the exception permanent,
even if the file comes to exist at a later time.
As a reminder, we use fs.watchFile only as a fallback in environments
where pathwatcher.watch is not available, such as on network or virtual
file systems.
Even though I think the fight is a bit futile, it is considered best practice to have newlines at the end of all files. At the request of meteor/meteor#7786, this commit adds newlines to the end of the new app skeleton `.gitignore` file. These skel files are used when generating new meteor apps so this avoids perpetuation of this problem into futrue generations. ;)
In an effort to beef up this PR, I also took the liberty of fixing the few other Meteor files which were lacking newlines (all `.gitignore` files)
