Thanks for the warning although I wasn't on planning on using
mismatched MTU for real operations :)
It was for the purpose of determining the effects of using the
different MTU that I was doing that.

Even if there wasn't the risk of a hang, for the sake of better
performance, it seems that matched MTU are better anyway. The sys time
component increased on the receiving side in relation to the
receiver's MTU but drops significantly (8~10%) when non-default MTU
are matched.
