-lthr vs. -pthread

[Julian Elischer]

this is a question for marcel,
but basically "this may change". In current code the thread_id of the
first thread is set to be equal to the PID. Marcel and I have discussed
reworking the thread_id code and in the new code this will possibly not
be true.

Under KSE teh original thread has probably exited.. and the one
availabel to run is number 100004. Under KSE threads are ephemeral, and
come-and go as needed.
(so the ID actually doesn't mean anything of rgeat significance)
