qmail-send dying

[mikeyg]

I have asked this on the mailing list but it seems the list is down right now or something, I tried to post 2 times and it has not shown up.  Anyways, it seems that either the qmail-lspawn or qmail-rspawn is dying and causing qmail-send to exit with the error "oh no! lost spawn connection, dying...".  I ktraced both qmail spawns and I have come up with this, here is the last 50 lines of both.
