Summary: Shell "crashes" on OS X Leopard

Initial Comment:
Not sure if this is Leopard (10.5.0) specific since I only just started using [shell].  After a command completes, about 20 seconds pass and then OS X reports that "Pd quit unexpectedly" – but Pd seems to continue running just fine.

Attaching a repro (just [ls( - [shell] ) as well as the crashlog.

I looked into this a bit - this is printed to the console when it
crashes:
__THE_PROCESS_HAS_FORKED_AND_YOU_CANNOT_USE_THIS_COREFOUNDATION_FUNCTIONALITY___YOU_MUST_EXEC__()


I found this quote on the apple support forums:
"
This is caused by programs that use the fork() or daemon() function in
combination with higher-level APIs. In Leopard you cannot use the
CoreFoundation (CF...) APIs on the child side of a fork() without following
it with an exec*() function. This has always been true, but Leopard is much
more stingy about this kind of thing.

To solve this issue, uninstall all third-party drivers and system
customizers, then reinstall them with the latest versions, and make sure
those versions have been updated for Leopard. Any drivers and background
software that use CF but haven't been updated for Leopard will continue to
output these messages, even though they may function fine. 
"

I guess the system() call doesn't count?
