On Linux, you can also use /proc/self/exe instead of a path with a pid
in it; on FreeBSD, it's /proc/curproc/file; and on Solaris it seems to
be "/proc/%ld/path/a.out", whereas "%ld" is the process id. All those
files are symlinks to your program.

Please note that proc is optional on FreeBSD, and that Debian
GNU/kFreeBSD has linprocfs mounted on /proc and thus behaves like the
Linux one.
