Mea culpa, Dave - I'm the one who introduced this change, and
thanks Thomas for filing it and pinging me.

This is not ugly in this case - not all signaling is available
everywhere, so the less ugly solution, which I've submitted as
PR https://github.com/ipython/ipython/pull/3075 is to check if a
signal is available before registering it.

SIGUSR1 is not available on Windows, but is on Linux and BSD
kernels. SIGINFO is only available on BSD kernels.

best,
