[on-discuss] Is port_get[n] intended to be a cancellation point?

[Jason King]

It's not clear from my reading of the man pages if port_get[n](3c) is
an intention thread cancellation point.  Looking at the cancellation
implementation, it strongly suggests port_get[n] is a cancellation
point (I'll probably test this sometime this weekend when I have a bit
more time to mess with things).  Assuming my suspicions are correct,
can anyone tell me if this is in fact intended (would seem logical)
and if it's merely a documentation lapse (i.e. I can depend on this
behavior)?
