[Click] write handler synchronization

[Roman Chertov]

Hello,
    I am making an element which will vary link properties based on a 
provided scenario file.  A user app will periodically communicate with 
the Click module via the read/write handlers.  Is it possible for 
run_task to execute while a write handler is executing?  This can 
potentially corrupt the data structure which houses the link events.  So 
I am curious if I need to add synchronization or not.

Thanks,

Roman
