Think, it traces to
gui/gtk.cpp:GtkGui::setInterval(unsigned int interval)
and similar methods for other frontends: gnash always run that periodic
low-delay timer, whether it needs it or not.
And that causes those unnecessary wakeups.

Plus, there may be more problems with /unpaused-by-gnash/ movies: can we
avoid running that timer for static pictures? Say, this one:
http://www.ixbt.com/power/ups/photos/riello/plug_dialog/pdg600/riello_pdg600_timepower_pc.swf
{looking in swfmill - not easy, it seems busylooping inside flash code};
or on paused-by-flash-||-button youtube movie? Well, I don't know gnash
code/flash internals to dig deeper.

Random thing found on LAN ;-) [after some googling] Seems, this one,

Well, judging by above, that does not matter, gnash would behave same on
anything.
