I keep finding more of these.

ACK.
Have you looked into some of the other stuff in the qemud_client struct?
For example, nothing inside #ifdef HAVE_SASL gets freed during
qemudFreeClient(). Quickly looking at the use of those items, it appears
it might be possible to be freeing up the client struct when one of
those is non-NULL, but I didn't read very carefully...
