Wonderful tool, that WINEDEBUG!
I'm very much a newbie too, and the WINEDEBUG stuff really helps me
getting just a little bit of understanding about what is going on. 
Love it.

In the manual here:

I've found that you can exclude those CriticalSection messages which
you probably don't care about.  That should give you a much smaller
file and faster execution times, which is always nice when you're

You need to put the following key/value somewhere in your registry -
the manual and winehq pages are, ahem, not very explicit about where
to put them, but supposedly somewhere under key named 'Debug'...:

"RelayExclude" = "RtlEnterCriticalSection;RtlLeaveCriticalSection"

Found a bit in a wine debugging tutorial:'Wild_Metal_Country'

Which explains nicely that what you see is an infinite loop, I think
somewhere in Wine's exception handling code, and that you should debug
with +seh to see what's going on.

Sounds hackish :-).

Quah?  Mebbe.  Easiest thing would probably be to make your app write
to stderr instead of that file it's using?

There's also a hack in the manual (see first link) that will send
WINEDEBUG messages to a file, but then again so will 2> ...
