The issue is the lack-of-fork in the Win32 API.  It's supported at the ntdll
layer, meaning that all the win32-ism's such as their thread-local storage
model don't survive the fork() at all.  For pure NT kernel code it would be
fine, for blended code (even the clib uses the Win32 API) it's very quirky.

For buggy modules you are absolutely right, it disrupts only the connection
which caused the instability - and requests which don't trigger the bugs
continue to work fine.

Same as in worker (for every thread within one process)
