Handle SIGTSTP in run-program process-status
As mentioned in #41 (comment 3164), SIGTSTP
is handled well in process-status
from run-program
. IT seems cmucl never gets a SIGCHLD
signal when the sub-process receives a SIGTSTP
. Curiously, cmucl does receive the SIGCHLD
when the sub-process receives a SIGSTOP
.
