Keep in mind that valgrind slows down the application _a lot_.  You will reach
high load much sooner than you would running without it.  It does make sense
that some of the behavior you are seeing could happen.  If the channel walk code
waits too long for the lock on a channel, it will skip it.  Though, it generally
doesn't happen unless there is a deadlock.  However, you certainly should always
see the summary printed at the end no matter what ...
