Thanks for these details!

Since we now use siglongjmp() within a signal handler, the not working on
non-unix part really doesn't change much as non-unix platforms won't have
signal handlers either! ;-)

We'll need to add platform-specific solutions to make name lookups timeout
properly on non-unix systems but also for multi-threaded unix programs (as
using a signal handler for that is no good).
