Hi Randy,
I didn't _forget_ 9.5.1(18), I just couldn't remember which paragraph said
that I/O subprograms are potentially and couldn't find the paragraph in my
quick review (;->). But, that answers my question, thanks!
Take Care,
Ed

You forgot 9.5.1(18): IO subprograms are "potentially blocking". (And thus
cannot be called from a protected object.) Thus, the question about
Priority_Ceiling is moot.
Of course, that doesn't say whether they REALLY are blocking.
