Are you sure? Doesn't sigsetjmp() call sigprocmask in order to obtain the current signal mask?
In the glibc I read:
int __sigjmp_save (sigjmp_buf env, int savemask) { env[0].__mask_was_saved = (savemask && __sigprocmask (SIG_BLOCK, (sigset_t *) NULL, &env[0].__saved_mask) == 0);
return 0; }
*sigh* things could be so easy if there was a working pselect()...
