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.
