Comment(by jdemeyer):
Replying to [comment:13 nbruin]:
> in ecl_sig_on(), you do a sig_on() BEFORE switching to the ecl signal
handler. That provides a window for an interrupt to still be handled by
the SAGE handler. Is that intentional?
Yes, it is intentional. It fixes the problem of an interrupt arriving
*before* ecl_sig_on() is called, I added a test to prove that it works.
