Subject: Using large memory segments with a telnet session

Thanks to the archive of this mailing list, I have discovered that you can 
use large memory segments with cygwin by modifying the registry key:

HKEY_CURRENT_USER\Software\Cygnus Solutions\Cygwin

and adding the value heap_chunk_in_mb (DWORD set to max memory amount).

The problem that I am having is that I am logged into a machine via telnet
using 
the inetutils. It appears that the registry setting is ignored for telnet
sessions. So 
I can't run large memory programs when logged in remotely.

The problem may be exaggerated by the fact that I am using roaming profiles 
and the registry for the user I am logging in as is stored remotely.

I have tried several things to no avail:
1. Setting HKLM\Software\Cygnus Solutions\Cygwin\heap_chunk_in_mb
I thought this might work since system wide mount points seem to be working
and these are set under HKLM. Didn't work.
2. Setting HKCU\Software\Cygnus Solutions\Cygwin\heap_chunk_in_mb for the
user running the inetd service. Nope.

I am running out of ideas. I am fairly sure that I can recompile the
cygwin1.dll and 
change the default heap size to get around this problem, but I would prefer
to
handle this as a configuration so that I don't have to recompile for every
release.

Any ideas?

Thanks

P.S. Why is the default 128 Mb? This seems ridiculously small.
