cfmodule threads

Question

Hi,
We have been having issues with server performance and under
heavy load JRun seems to hang. Dumps seem to suggest that the pages
that are hanging are waiting for another thread to become available
- however the line of code where this occurs always seems to be
where a cfmodule is called (not necessarily the same module as this
changes all the time.)
My question is: when calling cfmodule does it run under the
current thread or is another thread taken from the pool to run the
module and then control passed back to the original thread?

Hope I am making myself clear...

Thanks

I expect that the module runs in the same thread as the calling page. After all, modules and custom tags are designed such that, if they set a variable caller.x, then the variable x will at once be available to the calling page. If there were two threads involved, one would have needed to lock or synchronize somewhere.
