  It will break the at command, among other things...  When "at" saves your
enviroment for subsequent job execution, it goes through and saves all of
them.  The problem with this is that when the at job is later executed, at
tries to go through and restore all of the enviroment variables, including
the ksh-specific ones, such as RANDOM, PPID, PWD, RANDOM, SECONDS, and _
(last command line).  Now, at this moment I am not sure, but at least one
of these causes the "at" job to crash when it is restoring the enviroment.
It has been a while since I tried it - sorry if my memory is vague...
