actually not that much trouble. We just have plmalloc keep a list of
all memory allocations in a variable in the PLStream and plfree can
remove items from that list. Then we have a free all function which
gets called before the API returns, which frees anything left on the
list. This not only deals with memory leaks after a longjmp, but if we
miss a free anywhere it will also clean up any other memory leaks. I
have already implemented it in the plmalloc/plfree functions I've
written. I'm just adding the calls and I will forward it round.
