The problem is that we did not need to save/restore the signal mask,
for this was restored by the signal handler itself.

However the appropriate code was only executed when ECL was built with
threads, not in the default version. That is what was confusing me.

I have fixed this and uploaded a version that restores the signal mask
also in the single-threaded version of ECL.

When I find time, maybe I switch towards using sigsetjmp when available.
