The main difference here is fixes to memory segment allocation on Spur. ��Linux and Mac OS can now grow the heap to 2.9Gb or there abouts, and Win XP can grow to 1.8Gb. ��I'm interested in reports on other Windows versions that don't have XP's 2Gb user process address space limit.

CogVM binaries as per VMMaker.oscog-eem.779/r3018.
Rewrite memory allocation on linux for Spur. ��Arrange that the heap can grow
above 2Gb without any large initial alloc.
Rewrite platforms/unix/vm/sqUnixSpurMemory.c to stand alone. ��Use it in place
of sqMacMemory.c with Spur on Mac OS. ��Now Spur can grow the heap to 2.9Gb on
both linux (CentOS 5.3) and Mac OS X (10.6.8).
Rewrite Spur memory allocation on win32 similarly to unix. ��Can now allocate
up to 1.8Gb on Windows XP (which has a 2Gb address space limit). ��Add a flag
to indicate if the win32 exe is running as a console app and don't write to
the in-window console if so.
Fix some sign issues with free space tallying to allow Spur to shrink memory
and answer via primitiveVMParameter heap sizes above 2Gb.
Add longPrintInstancesOf:/longPrintInstancesWithClassIndex: for debugging.
Suggest reading a suitable README when the linux VM fails to spawn the heartbeat
thread.
Add parameter 54 on Spur to answer totalFreeOldSpace.
