Comment(by nbruin):
Nice cleanup! Two questions:
* 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? (It might even be a good idea if
that "clears out" the signal queue before switching to ecl handling,
because ecl will not be aware of any signals queued by SAGE, which might
cause them to grow stale)
* Juanjo's suggestion
http://sourceforge.net/mailarchive/message.php?msg_id=27127709 includes
using some macros from ecl's header files. Can that be integrated in
ecl_sig_on() etc? Since you are moving things to a .c file, using those
macros will be much easier. I gave some thought on how to import those
into cython but failed to come up with a solution.
