Re: heap_chunk_in_mb reg entry !?

HKEY_CURRENT_USER\Software\Cygnus Solutions\Cygwin\

Create a new DWORD value there called "heap_chunk_in_mb" that contains the
maximum amount of memory (in Mb) your application needs (watch the
hex/decimal toggle). Exit and restart all cygwin applications.

The default is 128 (i.e. 128Mb) if no registry key is set.
