It seems like the errlogFlush() on line 243 is returning before the
output of the preceding errlogPrintfNoConsole() has been seen by the
test's log listener.  Since pvt.count catches up it is clear that the
message isn't dropped, just late.

I can't fully explain the exact mechanism.  It's possible that the
short-circuit case of errlogFlush() is being hit.

There might be a race if errlogFlush() runs after errlogThread() finds
msgbufGetSend()==NULL, but before it tests the flush event.

I'm not sure this could cause this specific behavior though.
