I also vote for keeping gmetric in the game.  I have asked this question 
before and I now sense a chance to reissue it :-).  Here is goes:

Is there general interest in extending gmetric so that it can take a list 
of metrics, instead of just one ?

We have a situation where we need to feed in lots of metrics and thus
suffer from the resulting system calls.

Another thought I had to further reduce system latency was to daemonize 
gmetric and let it read from a local socket or pipe or whatever peopel 
think is most convinient.
