I think just closing stdin and stdout is likely to be enough, or maybe all file descriptors from 0 to $^F . The OS will close any others that have the close-on-exec bit set, and the close-on-exec bit is set by default by Perl's open function. Anybody setting this to something different probably understands the consequences. ----Scott.
