Some Pascals (maybe all?) supported a possible compromise where you
called a routine "mark()", did your allocs and later some sort of
super-free which would release everything back to the last mark()
call.  There was no need to call all in the same routine, just so long
as mark() was called earlier than the allocs and free. It could work
either stackwise (my preference) or take some sort of magic cookie to
identify which mark to clear back to (probably useful before a longjmp
after an error condition.)

This should be very easy to implement within C/Unix, even within the
current malloc schemes by just introducing a special mark cell into
the chain.
