[Openmcl-devel] Decreasing the size of the reserved heap

For bizarre reasons, I'm trying to get CCL to start with a lower
amount of allocated virtual memory.  But it seems that CCL is mostly
ignoring my request (according to top, CCL is still allocating 128g of
memory on Linux kernel 2.6.32-358.18.1.el6.x86_64).  I've spent a lot
of time searching for the cause, but it's time to ask whether there's
anything wrong with my command:

   scripts/ccl64 -R 4000000000

I know that the topic "Heap Allocation" (found at
http://ccl.clozure.com/manual/chapter17.3.html) uses the word "try" to
describe the attempt at only reserving small amounts of heap space.
But this is enough of a difficulty for my situation that I wanted to
ask anyway.  Is there something else I can try?  Is there a value in
the CCL source code that I can edit manually and then recompile?
