Sounds good to me.
The only down side is that both of those words are quite long.
This makes the safety notes visually long.
Any thoughts on a short form?

I mean to imply that I hope we need not add any other safety
notations aside from thread safety, signal safety, cancellation
safety, and reentrancy. I have not seen any other notes in other
Unices with the exception of fork1-safe in Solaris. Have you
seen any other kinds of notes we might prepare to need in the
future?
