[Gnash-dev] ExternalEventCheck selects w/100us timeout

[John Gilmore]

I'm poking into the cause of CPU time going to 100% while running gnash.
I posted some hints a week or two ago, but nobody followed up on them,
so I'm seeing if there's something simple that I can fix.

I'm having trouble figuring out why ExternalEventCheck is polling with
select() and a very short timeout every time around the movie_root
loop to see if a browser wants to talk to it over a file descriptor.

Shouldn't this file descriptor be included in the global select or
poll arguments that determine whether ANY I/O or timeout is ready?
There should be zero need to poll this file descriptor.

Fixing this will eliminate a bunch of the CPU burning in current
trunk.  However, since this code appears to be new since 0.8.7, it
won't fix the CPU burning behavior of gnash, all by itself.
