Patch: Add Log Output Sync, and Add Status Command

[sabat]

Hi everyone --

I just uploaded a patch to the current revision (0.1.2) that does two
things:

1- calls 'sync' on the log descriptor after opening, so that the OS
doesn't buffer the log messages as they're written. (Simply put, you
see messages immediately as they're written to the log, instead of
having to wait eons.)

2- adds a 'status' command, which checks for the existence of the pid
file and then runs Process.getpgid on the PID. I did see that someone
else had added a patch that has a check to see if the daemon process
is alive; however, it runs /bin/ps to do the check, which would
obviously not work on Windows, and is (IMHO) a little less elegant
than having Ruby do the check itself.

OK, I lied -- I've uploaded an updated patch that also handles the
duplicate instance problem. I also took a liberty
by moving messages to constants defined in SimpleDaemon::Base.

Hi.

Good to see that this groop is still alive. :)
The sad thing is that maintainer seems to be lost.

"gem search" shows that several clones available... may be there is a
point in patching one of them.
