I had this happen too.

I strace'd semodule & it was blocking on a write() call to a pipe connected
to the parent process. So I killed semodule, and now the parent (the /bin/sh
process for the %post script) blocked on writing to its parent  (yum). So
I killed that too, and now yum blocked writing too. Finally I Ctrl-C'd
yum, and it spewed a bunch of warning messages to stderr, which clearly
came from semodule.

So, two issues - semodule should redirect all its output to /dev/null in
the %post script, and  yum should make sure it consumes both stdout/err
from any scripts it runs so they don't block.

Unfortunately, I lost the strace logs before I could file a BZ report and
my other machines are fine with the update.
