yppush going into an endless loop

Here is more information. I was able to capture the output of yppush on
one of these occurrences:

yppush: transfer of map netid.byname to server <local-machine> failed
yppush: status returned by ypxfr: Master's version not newer
yppush in malloc(): error: recursive call
yppush: warning: exiting with transfer to <local-machine> (transid = 1098286624) still pending
yppush in free(): error: recursive call
yppush: warning: exiting with transfer to <local-machine> (transid = 1098286624) still pending
yppush in free(): error: recursive call
yppush: warning: exiting with transfer to <local-machine> (transid = 1098286624) still pending
yppush in free(): error: recursive call
yppush: warning: exiting with transfer to <local-machine> (transid = 1098286624) still pending
[...]

Something fishy is happening here, maybe the SIGIO handler is called at an
unfortunate time. I'll patch around yppush to get a core dump at that point.

Thomas.
