It has the hazard that environment variables are visible in the
process listing anyway on many platforms. On Linux, try "ps auxeww";
on MacOS X, try "ps -efEww". At a quick glance, it seems that on both
of those platforms you have to either be root or be the same user that
owns the process, but I'm not sure that every platform will have it
locked down that tightly and even that might be more exposure than you
really want.
