Let me remind you what has to be done.

We need to use set_proctitle() for those platforms that have it.  I
don't have it here, but Linux does.

Second, we need to determine if set_proctitle is a cheap function by
looking at the library source code.

Third, we need a 'configure' test to see if the modification of argv[0]
displays in the ps output.

If modification of argv[0] works, use it, as the current code does.

If not, then if set_proctitle() is available, use to change the backend
'ps' display on backend startup, and if it is cheap, use it to change
status for every command.

If a platform has neither, use the sendmail code to change the ps
display on backend startup only.  The sendmail code it so slow to use
for every command, I think.
