Ioannis, could you perhaps share some of your w.i.p. code regarding
signalfd-based signal handling in guile? Adding to what Ludo'
mentioned, I imagine you are running into some peculiarities regarding
guile's way of handling signals, so I would recommend to start
lurking on #guile if you did not do this before now, so you can interact
with the folks with the most expertise regarding the problems you
might be facing :-)
