FPC's heap manager and IO functions (writeln/readln) are *not* thread 
safe. That's probably what's causing the crashes. Add the cmem unit (from 
the "packages" units) as the first unit in your "uses" clause, then 
you're at least safe on the memory management side. You can't use heaptrc 
with it though.
