[jQuery] JQuery blockUI plugin - support for queueEmpty function

[jQuery] JQuery blockUI plugin - support for queueEmpty function


How would I extend blockUI to have a function callback for when the
queue is empty? I want to use something like this in a project where
I have several queued ajax requests, but I only want to call blockUI
on the first request and unblockUI when the queue is empty.
Thanks,
Russ
