out-of-sync IDs received from the server

[tony2001]

It seems that somehow it's possible to get out-of-sync replies from the server. We haven't really figured how exactly, as it happens under high load, but it's definitely reproducible.
There's an assert() in the sources that checks for exactly that situation, but it's disabled when PHP isn't built with --enable-debug, so basically the extension checks for this situation and does nothing.
I believe at least an exception should be raised in this case or maybe you should even close the connection - you can't continue using it anyway. At least, that's exactly what we've tried to do, but failed due to issue #56 .
