Hi,

> 
> Create a new DWORD value there called "heap_chunk_in_mb" that contains the

Hm, I created HKEY_CURRENT_USER\Software\Cygnus
Solutions\Cygwin\heap_chunk_in_mb
and set it to 640 decimal (I have 640MB RAM). I restarted all cygwin
programs (I even rebooted) but it didn't help. Whenever the program
tries to allocate more than 240MB I get an out of memory error. 

So the program can allocate more than the default 128, but can't get
500MB as it wants. Any idea what's going on ????

P.S. From the windows side the 640MB are recognized without problems.
That means the TaskManager reports that 640MB are available.
