989	High CPU usage when calling signal handler multiple times	Mario Domenech Goulart		"Here's an example to demonstrate the aforementioned behavior:

{{{
;; Press C-c multiple times in an interval < 20s

(use posix)

(set-signal-handler!
 signal/int
 (lambda (signal)
   (print ""caught signal"" signal)
   (sleep 20)))


(let loop ()
  (sleep 1)
  (loop))
}}}

I cannot reproduce that behavior on 4.7.0.  Peter mentioned on IRC that b7995839c0b481280bdeda117eb68bc0e78a40bf triggered it."	defect	closed	critical	4.9.0	core libraries	4.8.x	fixed	signal handling
