Unless SVR2.2 has added something interesting, which I doubt but can't
quickly check on, the kernel won't be hurt.  An awful lot of programs
want to close all file descriptors and have the number "20" wired in,
either as a named constant from param.h or simply a literal number.  If
all the code you write that actually uses those extra descriptors is
careful to always close them before doing an exec(), shouldn't be much
of a problem.
