git-daemon memory usage, disconnection.

I'm running git-daemon from xinetd and it seems a little greedy...

Cpu(s):  2.7% us,  6.4% sy,  0.0% ni,  1.7% id, 87.7% wa,  1.4% hi,  0.0% si
Mem:    253680k total,   250076k used,     3604k free,      568k buffers
Swap:   500960k total,   500864k used,       96k free,    24696k cached

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND

30208 nobody    18   0  140m  14m 7632 D  0.3  5.9   0:15.23 git-pack-object

Now, this wouldn't be _so_ bad if there were only two of them running. The clients for the other four have actually given up and disconnected long ago, but git-daemon doesn't seem to have reacted to that.
