you propose <machine/setjmp_jblen.h>.  actually, i think it should
simply be <machine/setjmp.h>.

also, i believe that jmp_buf (and sigjmp_buf) should be arrays of
'long's rather than arrays of ints.

this doesn't make much difference... unless you're on a 64-bit RISC
machine that traps writes of 'long's to non-long-aligned addresses,
and which only aligns arrays of 'int's to int (i.e. 4-byte) alignment.

thoughts?  if i hear no objection, i'm going to implement both of
these suggestions tomorrow.
