That's interesting to know. Not something to rely on, I suppose. Otherwise
it'd make for a decent way to code self-unpacking archives, like MSDOS does...
(Then you don't have to worry about what the file was named, or where it
was invoked from, you just find the descriptor and read from it....)

I think RELOC comes with a program that patches this little bug. Lawrence Y. Chiu; University of California, Berkeley.
