[jQuery] [feature request] blockUI. To have a cancel button appeared after n seconds if the blockUI not unblocked


Dear sir,
From time to time, we might have code which using blockUI that cannot
unblock-ed properly. In that case, user can do nothing but refresh the
whole page and which is not what we expected at all.
I suggest the following options
1. cancel_dealy: which will appear a close button, such as an
element within the blockui div and have class ".blockui_close". When
click it, unblock will be called.
2. cancelCallback: an call back function if cancel clicked
3. successCallback: an call back function if blockui called instead
of canceled
Thanks!
