After some poking around, I noticed that Linux (at least the 2.1.120
release) offers such a mechanism already if the /proc filesystem is
built into the kernel.

$ ls -l /proc/self/exe
lrwx------   1 kodis  kodis   0 Oct  4 19:13 /proc/self/exe-> /bin/ls*

... and of course there should be the argv[0] and $PATH fallbacks
provided for systems that don't offer this feature.
