I would be very much interested in seeing your code.  I've recently been
writing a number of C tools, including a memory allocation module, and I'm
always eager to see how others approach the same problems.

I've rolled my own allocater in order to integrate an exception handling
module that I've been working on for awhile: if the allocation request can't
be satisfied with the available memory, an exception is raised, throwing
control back to the most recently activated handler.  This frees the 
programmer from having to clutter his or her code with a lot of error checks,
since if the allocation call returns at all, it has successfully filled the
request.

My exception handling module is probably also a good candidate for posting,
is there any interest out there?  It currently has compile-time conditionals
which allow it to be compiled in THINK C or MPW for the Mac, or in GNU C on
the TI 1500 (and probably any other 680x0 based machine, but I don't have any
others to try it on).
