Just looking at it, I think that the logic in canAcceptConnections got
broken by somebody in 8.4, and then broken some more in 9.0: in some
cases it will return an "okay to proceed" status without having checked
for TOOMANY children. Was this system possibly in PM_WAIT_BACKUP or
PM_HOT_STANDBY state? What version was actually running?
