FWIW, I see the following on both 4.05 Solaris and 4.08 Linux: occasionally
Netscape "freezes", and forcing it to receive an X event (usually by moving
the mouse into or out of its frame, since I run with backing store)
unfreezes it. Sometimes this must be repeated a few times before it notices.
This along with your report makes me think that Netscape is doing something
*really* stupid such as internal preemptive multitasking with the pipe
feeding a scheduler routine which looks to see what requested scheduling by
writing to the pipe and dispatches with longjmp() or abuse of throw/catch.
The possible failure modes, if anything doesn't work exactly as the
author(s) predicted, are mind-boggling.
So pre7 does something Netscape doesn't quite expect --- it may well be
*valid*, just not what they tuned the above monstrosity for on Linux --- and
Netscape goes into a tailspin. Surprise.
I always wondered how they simulated multithreading. Somehow I think I now
know... it seems just about repulsive enough to fit :-)

We are Linux. Resistance is an indication that you missed the point.
