| Note: A future revision of POSIX later than the 2008/2009 one may drop the |
| functions @code{_setjmp} and @code{_longjmp}. Still, in 2008, on all |
| systems which have @code{_setjmp}, it is the fastest way to save the |
| registers but not the signal mask (up to 30 times faster than @code{setjmp} |
| on some systems). |
