Race conditions in event handlers

[sergun]

Hello!

What can you advise to fight race conditions in ipywidgets event handlers.
For example when you click on some button very quickly many times handlers are called also many times and their executions can interleave.

What synchronization mechanism can you advise for such case?

What do you mean their executions can interleave? The button click events should be sent in order to the kernel, and if it's python processing the button events, the python code executes synchronously and in the order the events were sent. Can you clarify what race condition you are seeing? It would also be really helpful if you gave code to replicate the issue.
