[Openmcl-devel] Clozure CL on ARM, Ubuntu GNU/Linux, repeatedly creating processes eventually fails with a Kernel memory allocation failure

[Gary Byers]

The same bug affects both ARM and X86 versions; some stack space used by
a thread isn't reclaimed when the thread exits.  That's fixed in the trunk
souce as of r15995; I haven't yet checked to see if it affects the release.

The bug is more likely to cause a 32-bit implementation to run out of
memory (or address space) than it is to affect a 64-bit implementation,
simply because there's more of both on a 64-bit machine.
