wayland multi-threads interface bug

Wayland may have interface bug when multi-threads programming.
This is a very serious bug in every version of wayland. 
It only occurs when multi-threaded programming,but it may cause an "S" level
Error(screen freeze or program crash).
Briefly,a wl_proxy's property is still being modifying in a thread,while
another thread may have sent it to server.Namely,Any modification of a
generated callback wl_proxy may be ineffective,as other thread may have read
and dispatched its corresponding events.
I have a detailed description of the problem and my solution in the attachment.
Please refer the attachment for detail.
If you have any question with the bug,pls feel free to contact me.
