level. Each request gets a single thread for all it's execution. Certain
tags circumvent this (such as by specifying a timeout of zero on CFEXECUTE),
but they're really severing themselves from the request thread, not just
executing simultaneously.
If you really want to multithread a request, I think you'll have to drop
down into Java and do it that way. Of course, you'll lose all the
simplicity of CF if you do that.
