* We can't use shared_from_this() here because JOLTing occurs prior to
* TLS being set up.
*
* We also can't use getSelf() as yet for the same reason: getSelf()
* requires TLS to be set up.
*
* To obtain a sh_ptr to the caller, we just supply the mrntt thread since
* JOLT is always invoked by the mrntt thread. The JOLT sequence that the
* CRT main() function invokes on the mrntt thread is special since it
* supplies cmdline args and envp.
*
* To obtain a sh_ptr to the target thread, we explicitly look it up in the
* Mind object's collection of component threads.
