No, you can't, unfortunately:

http://svn.python.org/view/python/branches/release27-maint/Modules/signalmodule.c?revision=85145&view=markup

if you scroll down to getsignal, you'll see that it just reads from a
global table it keeps, which is filled by signal().  A C-installed
handler can call the raw PyOS_setsig() without updating the table, and
getsignal() will be none the wiser.
