non-root process and PID files

[Dan Langille]

If a process starts up and does a setuid, should it be writing the 
PID file before or after the setuid?

Two methods exists AFAIK:

1 - write your PID immediately, and the file is chown root:wheel
2 - write your PID to /var/run/myapp/myapp.pid where /var/run/myapp/
    is chown myapp:myapp

Of the two, I think #1 is cleaner as it does not require another 
directory with special permissions.

Any suggestions?
