Is it possible to incorporate such tests into Emacs, and write some
Lisp to execute the tests and report the results?
I'm asking because it's hard to use this test as-is on MS-Windows,
since all of the related functions used by the Windows build are
reimplemented by Emacs sources, they are not in any system library,
and so linking a stand-alone test program is not easy.
TIA
P.S. If memory fragmentation is what you worry about, then doesn't
ralloc.c free us from this, on platforms that use it?
