Summary:                    QUEUE_MEMBER and QUEUE_MEMBER_COUNT tries to destroy
queue, leading to segmentation fault
Description: 
Loops for queue_function_qac and queue_function_qac_dep are identical, so
both those functions should be affected.

Backtrace shows that queue_unref is calling destroy_queue, which however
calls queue_unref again, thus leading to recursion, limited by queue member
count.

  Found a few places where queue refcounts were counted incorrectly.  Also
add debug statements.
