I have run into programs that fail when run by safeSpawn but succeed with  
spawn.  I tracked it down in one (python) and it seems to be due to  
uninstallSignalHandlers.  When run by safeSpawn, the program reports errors  
from wait.

Arguably applications should perhaps be more robust, but it seems worth  
fixing here.
