As an application level gateway, the purpose of DeleGate is to do some
meaningful interpretation on application protocol.  So I've seldom
cared about such performance of which cost and delay can be far smaller
than that in protocol interpretation.  DeleGate does not cover the field
which should be achieved far more simply and effectively in circuit level
proxies or in lower protocol layers.

But in this case of "tcprelay", I suppose the most part of the delay is
from the cost of fork() of DeleGate for each connection, which should
be suppressed.  It will be done as the enclosed patch.

Cheers,
Yutaka
