[Yum-devel] [PATCH/RFC] Don't exit immediately on lock held

[Jeremy Katz]

Per a suggestion on fedora-devel-list from Hans de Goede, the following
makes it so that we don't immediately exit on the command line if the
lock is held by another process.  Instead, we spin checking every two
seconds to see if the lock has been released.  This helps in the case
where, eg, yum-updatesd is downloading metadata so that you don't have
to guess when it's done.  And if you don't want to wait, ctrl-c exits
immediately.

Other opinions/thoughts?
