mscorsvw compile worker threads live view

Hello folks,

apparently it's a matter of triggering GAC update often enough to hit it ...

With .NET Frameworks 2.x/3.x installed:

--- snip ---
$ wine "c:\\windows\\Microsoft.NET\\Framework\\v2.0.50727\\ngen.exe" update
--- snip ---

Another orphaned process (wpid=0x19) with one remaining thread blocking on heap
lock:

--- snip ---

I managed to attach a debugger fast enough to catch a long running worker that
is still alive (some seconds) - unfortunately that one exited cleanly.
Usually around 13-14 threads, many of them RPC workers.
See attachment for reference.
