Except it doesn't work yet.

In some complex git completion --- reproducible only in one set up ---
the heap allocation is apparently going out of bounds.  Yet I've checked
and nothing seems able to happen that can affect this.  If I add
debugging, the same pointer is reported as returned from zhalloc() that
is later claimed to be out of bounds.  Yet with more debugging there's
no popheap() or switch_heap() happening, as by eye there can't be.  I'm
a bit stuck; how can a piece of memory returned by zhalloc() suddenly go
invalid?

valgrind agrees with gdb but doesn't give any more help.

Maybe we're just running out of memory after all?  That's a pretty big
stack...  I think it's a clue that the address reported as failed
usually ends in three 000's while as you'd expect the allocated address
is basically randomly 4-byte alligned in general.  A further clue is the
crash is never quite in the same place twice, just in some pattryrefs()
within igetmatch().

pushing and popping the heap locally doesn't work as we need to pass
stuff back on the heap.

Maybe I should just go back to zalloc().
