I can reproduce it with

/src/emacs -Q -batch -eval '(dotimes (_ 100)
  (start-process "foo" nil "sleep" "0.2")
  (igc--collect))'

I would move most of the work out of signal handlers.  The signal
handler could put the work in a "async work queue" and then return.  The
actual work is then processed by maybe_quit.

Sending the work to a helper thread would be nicer, but probably not a
realistic option with Emacs.
