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.
