=for comment core_thread_start() TBA
The core_thread_start() function informs the core that the provider has started
an interest in the current thread. The core will inform the provider when the
thread eventually stops. It must be passed the I<handle> for this provider, as
well as a callback I<handfn> which will be called when the thread stops. The
callback will subsequently be called from the thread that is stopping and gets
passed the provider context as an argument. This may be useful to perform thread
specific clean up such as freeing thread local variables.
core_get_libctx() retrieves the library context in which the library
object for the current provider is stored, accessible through the I<handle>.
