Hi Daniel,

Replying to a message of Daniel Lynes to Mike Burgett:

The above doesn't track with the docs on DosWaitThread, which claims it
takes a PTID, not a TID (a pointer to, instead of pass by ref.).  This
makes sense, since it also says it returns the TID of the thread that
exited in the location pointed to by the TID pointer.

The tib is the thread info block, but the thing I wrote above is the tid
stored in the tib. (aren't these ibm abbreviations fun? :)

I don't want to kill it, I want to wait until it's finished processing, so
that it doesn't get killed when thread 1 exits.  It will die normally when
it's done, I just want to wait for that to happen... 

Thanks,
Mike
