-### Issue Closure
-
-Bug reports will be closed if the issue has been inactive and the latest affected version no longer receives support. At the moment, Electron maintains its three latest major versions, with a new major version being released every 12 weeks. (For more information on Electron's release cadence, see [this blog post](https://electronjs.org/blog/12-week-cadence).)

-### Languages
-
-We accept issues in *any* language.
-When an issue is posted in a language besides English, it is acceptable and encouraged to post an English-translated copy as a reply. 
-Anyone may post the translated reply.
-In most cases, a quick pass through translation software is sufficient.
-Having the original text _as well as_ the translation can help mitigate translation errors.
-
-Responses to posted issues may or may not be in the original language.
-
-**Please note** that using non-English as an attempt to circumvent our [Code of Conduct](https://github.com/electron/electron/blob/master/CODE_OF_CONDUCT.md) will be an immediate, and possibly indefinite, ban from the project.
+### Issue Maintenance and Closure
+* If an issue is inactive for 45 days (no activity of any kind), it will be
+marked for closure with `stale`.
+* If after this label is applied, no further activity occurs in the next 7 days,
+the issue will be closed.

+  // Chromium has its own TLS subsystem which supports automatic destruction
+  // of thread-local data, and also depends on memory allocation routines
+  // provided by the CRT. The problem is that the auto-destruction mechanism
+  // uses a hidden feature of the OS loader which calls a callback on thread
+  // exit, but only after all loaded DLLs have been detached. Since the CRT is
+  // also a DLL, it happens that by the time Chromium's `OnThreadExit` function
+  // is called, the heap functions, though still in memory, no longer perform
+  // their duties, and when Chromium calls `free` on its buffer, it triggers
+  // an access violation error.
+  // We work around this problem by invoking Chromium's `OnThreadExit` in time
+  // from within the CRT's atexit facility, ensuring the heap functions are
+  // still active. The second invocation from the OS loader will be a no-op.
