I've been trying to minimize the memory requirements of the new version
of my _Launch program and I have been successful in all but one area.

To get an icon from an application, I call OpenRFPerm(...fsRdPerm) on
that application.  The resource map, and other Resource Manager memory
structures, take up a HUGE amount of memory.  For example, getting the
icon from THINK C requires 82K of contiguous space in my heap.

Is there are way to tell the Resource Manager to take up less space?
If not, can I request another (temporary) heap zone?
Or, how can I make the Resource Manager use some space which I get from
a Multifinder Temporary NewHandle call?

Any suggestions would be much appriciated.
