[Click] mutex on click

[Giovanni Di Stasi]

I have some handlers in the router configuration that are called from time to 
time by an user space process. These calls can modify structures that are 
used by click elements. Do I have to lock those structures when I modify them 
or are the handlers executed by the same thread of click elements?
How many threads does click use (in user space and in kernel mode)?

Thanks.
