This may be a Win2000 problem, not a cygwin problem...What service pack 
are you running?

You can try one more thing:  after you run out of memory and kill 
mozilla, exit all your cygwin processes, and check to see if the 
cygwin1.dll file is locked (try renaming it using windows explorer, but, 
remember to restore it's original name after).

Then open another bash shell and check the memory info.
