[Click] Multithreaded Click Element?

[Eddie Kohler]

(1) Please upgrade your Click installation.  Use the CVS version if  
possible, or the 1.5.0 version recently released.

(2) User-level Click does not support multithreading at all.   
Multiprocessor support is implemented in the Linux kernel.

(3) What does your element do?  Why do you believe multithreading  
will help?  Are you running Click on a multiprocessor machine?  There  
may be a better way.
