FIXED: If an error is signaled during taskmaster thread creation, the taskmaster-request-count slot is not decremented

Mailing-list thread: http://lists.common-lisp.net/pipermail/tbnl-devel/2012-August/005789.html

If an error is signaled during taskmaster thread creation (such as the
"getpeername": ENOTCONN error signaled during the generation of the thread
name), the body of the unwind-protect is never reached, and
taskmaster-request-count is never decremented. The counter eventually reaches
taskmaster-max-thread-count, preventing further requests to be processed by
hunchentoot.
