Debug log

This bug is about StormFront.exe from Simutronics.  The application works fine
for awhile, but at some point certain widgets in the app stop updating.  I
believe this is due to the message I'm seeing in the debug log (see attached):

fixme:win:alloc_winproc too many winprocs

The time it starts appearing coincides with the widgets not updating.  The
longer that the application runs, the more messages that are emitted.  I ran it
for about 4 hours and saw around 20k messages.

I did some code spelunking and tracked it down to this file:
https://github.com/mirrors/wine/blob/master/dlls/user32/winproc.c#L298

It seems like MAX_WINPROCS could be increased, and it might alleviate the
problem, but would probably just make it take longer to manifest.  (Since it
only manifests after using the app for a little while, now).

I am using Crossover Mac 12.2.0 (I am not sure which version of wine this is).

My question is twofold:
1) How hard would it be to actually reclaim these winprocs rather than leak
them?
2) If that doesn't work, is there some way for me to increase the MAX_WINPROCS
constant and recompile user32.dll to use for just one bottle in CrossOver?
