[Slightly OT and very much tongue-in-cheek . . .]

Why do all the cool things to play with (servers and worker spaces and TRAP and 
. . . ) require authorized code?  That keeps inquiring minds from experimenting 
and learning the cool things on our own (since no one seems to want to actually 
pay for learning anything these days).

Subject: Re: Is TCBSENV propagated to child TCB by ATTACHX

EXTERNAL EMAIL

Only if the attacher is authorized and asks for that to be done, by 
setting bit TCBSENVP (the "P" stands for "propagate") in its own TCB prior 
to the ATTACH(X).
If the bit is on, the bit and the value are propagated to the daughter 
TCB.
