Subject: [PATCH 1/2] Change atom.sh not to spawn a sleep process every second
 on --wait

As sleep(1) is not a bash builtin, every second a new process is spawed.
To  prevent this, the POSIX read can be used instead.
Since it is (required to be) a bash builtin, it is immediately killed along with bash unlike a longer running sleep would be.
In case stdin is e.g. /dev/null for whatever reason (this would break EDITOR=nano), sleep is still kept to prevent a tight loop.

Subject: [PATCH 2/2] Use a named pipe instead of the tty

Works even if stdin is not a terminal.

Some programs can replace a fifo with a named pipe, which would break this.
For example: rsync without --specials
