Another random/quick question...

Isn't it the case that libunwind's setjmp/longjmp implementation
doesn't suffer from the "non-volatile variable foo may be clobbered
by `setjmp'" problem that normal setjmp does? That is, all variables
are restored, even non-volatile variables modified after setjmp().

If so, that might be worth mentioning as an additional benefit.
