Ben,

I did think of one issue. This is using non blocking IO after the connect
completes. It appears that a delta is that the logRestart thread is now
doing the periodic flush for *multiple* logging circuits. Therefore, if one
of the log circuits isnt flowing for whatever reason (disk full, marginal
circuit, server system power off, etc), then all of the other log circuits
will not be flushed untill logClientSend is called and the specified message
will not fit (the buffers capacity is exceeded). Since the internal IP
kernel timeouts for circuit disconnect can be quite long this might prove to
be problematic.
