I see the samething also, however my CPU is under 5% so it may not be
the gettimeofday causing your issue. I looked this up under upstream
SVN, there are a few references to it being an issue with the IVTV.
ivtv-0.8.2 and newer have said to fix the issue.

Also I do believe there is atleast 1 animated theme.

Bug description:
Mythfrontend constantly uses about 15% CPU which is enough to cause heat problems in my quiet frontend box.  And it wastes power too of course.

When connecting to the process with strace to see what's going on, here's what we get repeating as fast as the terminal can print it:

stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=3543, ...}) = 0
read(7, 0x13a9eb4, 4096)                = -1 EAGAIN (Resource temporarily unavailable)
poll([{fd=3, events=POLLIN}, {fd=8, events=POLLIN}, {fd=7, events=POLLIN}, {fd=11, events=POLLIN}], 4, 13) = 0 (Timeout)
read(7, 0x13a9eb4, 4096)                = -1 EAGAIN (Resource temporarily unavailable)
read(7, 0x13a9eb4, 4096)                = -1 EAGAIN (Resource temporarily unavailable)
poll([{fd=3, events=POLLIN}, {fd=8, events=POLLIN}, {fd=7, events=POLLIN}, {fd=11, events=POLLIN}], 4, 0) = 0 (Timeout)
read(7, 0x13a9eb4, 4096)                = -1 EAGAIN (Resource temporarily unavailable)

And /etc/localtime on my system is this:

root@ubuntu:~# ls -l /etc/localtime
lrwxrwxrwx 1 root root 30 2010-06-04 09:37 /etc/localtime -> /usr/share/zoneinfo/US/Central

So it should be valid.

Using lsof indicates nobody is using the file.
