Maybe, you're missing my point. I'm trying to avoid DR6 altogether.
And I can do it on some platforms. However, some Unixes seem to be
crippled and I'm trying to provide a reasonable fallback for them.
BTW if we forbid sending SIGTRAP to a Wine process, there will be more
such platforms. AFAIK SIGTRAP is only sent internally by wineserver
for DebugBreakProcess(). I'll have a look at it.
