/* This function abstracts the thread creation for modules by allowing you to pass a function ptr and
a void object and trust that that the function will be run in a thread with arg This lets
you request and activate a thread without giving up any knowledge about what is in the thread
neither the core nor the calling module know anything about each other.
This thread is expected to never exit until the application exits so the func is responsible
to make sure that is the case.
The typical use for this is so switch_loadable_module.c can start up a thread for each module
passing the table of module methods as a session obj into the core without actually allowing
the core to have any clue and keeping switch_loadable_module.c from needing any thread code.
