This patch is the kind of thing I mean.  It has an ugly aspect but it
does the job (maybe somebody can suggest a way around the ugliness).
I've bootstrapped but haven't run the testsuite.  The numbers passed
to VEC_alloc are guesses.  They should be large enough to be
sufficient for most cases, but not so large as to waste stack memory.
I'd like to hear suggestions for what the values should be.
