Hello!
This is a proposal to address issue with wrong exit codes from a Java
processes on Windows.
In order to avoid a race, calls to _endthread(), exit and _exit() are
explicitly synchronized.
We allow simultaneous calls to _endthread() by multiple threads.
However, at the time exit() or _exit() is called, no calls to
_endthread() are allowed.
Some instrumentation added with JDK-8055338 remain in the code to help
diagnose the failures if they still occur.
