First, my apologies for the very late reply. I did read your answers and
worked on them, but didn't have enough good data to reply.
What I found is that something in enlightenment goes into a tight loop
if I SIGSTOP a program like firefox-bin.
I tried unloading all modules and the tight loop does not stop, so I'm
guessing it must be the e17 core? (I was hopeful that the pager was
maybe hanging on trying to snapshot a stopped process window).
Any idea where to go from there? Can you reproduce on newer vesion of
e17 than what I have?
(launch firefox, sigstop it, strace enlightenment, and see whether
you get the strace bit I have below)
Thanks,
Marc

strace shows this in a tight loop
recvfrom(9, 0x24990b4, 4096, 256, 0, 0) = -1 EAGAIN (Resource temporarily
unavailable)
recvfrom(9, 0x24990b4, 4096, 256, 0, 0) = -1 EAGAIN (Resource temporarily
unavailable)
poll([{fd=9, events=POLLIN|POLLOUT}], 1, 4294967295) = 1 ([{fd=9,
revents=POLLOUT}])
writev(9,
[{"\214\3\n\0k\22L\1m\22L\1\6\4\30\0\0\0\0\0\6\4\30\0\31\0\0\0\30\2\0/"...,
40}, {NULL, 0}, {"", 0}], 3) = 40
recvfrom(9, 0x24990b4, 4096, 256, 0, 0) = -1 EAGAIN (Resource temporarily

Not sure what 9 is:

I couldn't track what socket this was, but I figured out that the tight
loop above happens when I kill -STOP some processes, and I do indeed to
this on batteries to save CPU cycles:
killall -STOP chrome chromium firefox-bin xmms mplayer pidgin procmeter3
plugin-container
It seems any time I stop a process, eventually enlightenment notices and
loops on that recvfrom loop.

Thanks for that other tip.

Thanks for that one, that's good to know.
Unfortunately, it seems that unloading all my modules didn't fix this
problem. I went in utilies and unloaded all the modules.
Then I went in system and unloaded everything too.
It did not stop the tight loop, but still that's good to know.
Thanks,
