I found a small bug/typo in the CCL specific code in the with-timeout.lisp file, which makes the trivial-timeout library not to function properly on CCL.
File: with-timeout.lisp
Original code:(Line 87 and 88) (* ,gseconds #+(or openmcl ccl) ccl:*ticks-per-second* #+digitool 60)
Fix:(Line 87 and 88) (* ,seconds-symbol #+(or openmcl ccl) ccl:*ticks-per-second* #+digitool 60)
