I'd just noticed that myself.  Perhaps it is "unreleased", as the T
2.8 release notes used to say of experimental things.

It works the other way too: the LOCALE special form has stopped
working despite being documented in the manual and in Stephen Slade's
book.  Nonetheless, I suspect the release notes cover most of the
changes (they cover the LOCALE one) and so expect that the number of
further surprises will be small.

I have not tried rebuilding T, but I have no trouble suspending it
with csh job control on a Sun.

Why, yes: I have one, and I know of at least two others.  We should
keep in touch.
