clone: bsd shell portability fix
When using /bin/sh from FreeBSD 6.1, the value of $? is lost
when calling a function inside the 'trap' action. This
resulted in clone erroneously indicating success when it
should have reported failure.
As a workaround, we save the value of $? before calling any
functions.
