I'm not sure what exactly is happening. I found one bug in RUN-PROGRAM, but
unfortunately unrelated to your case. Basically it seems shells don't like
being run the way SBCL prefers to run its sub-processes.

A workaround is simple, though:

 (define-alien-routine system int (command c-string))
 (system "/bin/sh")

Out of curiosity, what do SIGINT and SIGSTOP (C-c and C-z) do with
the Allegro shell-command?
