setproctitle is a cute hack that happened to work on BSD when sendmail
was written. The code is incorrect, just like code that assumes that
there will be an empty string at address zero, but it happens to work
on some systems. Until recently Linux was among the systems where
this incorrect code happened to work.
Since the code is incorrect, it is protected by a DO_PS_FIDDLING
define in the mount source. One of these days I should turn this define
into something figured out by configure.
setproctitle is the kind of stuff I am happy to see broken.
