Netscape 4 had a habit of going into interminable stalls :)

Kernel events without kevents Posted Mar 15, 2007 12:50 UTC (Thu) by pphaneuf (guest, #23480) [Link] Ah, there are many ways in which to wedge one-self, but thankfully, I think the simplest ones were indeed avoided. ;-)
The way Netscape 4 would wedge itself the most often for me (because I would often strace it when it did, since I was working on a big event-driven single-threaded program as well, and I'm curious to boot!) was to be reading the same file descriptor over and over, getting zero, and not getting the hint, for some reason.
I suspect there was a bit of code that wanted to do just the ONE synchronous thing, and of course, it screwed up and blocked the whole program. Tsk tsk tsk...
