Try the following experiment (on 2.2 and mabye 3.0):
1. Create a named pipe
2. Start typing into it using cat
3. Hit control-C as many times as you want
You'll see that the process will not die even with kill -9,
as it is stuck in uninterrupible disk sleep ("fifo").
But as soon as you read from the other end of the pipe,
the process exits.
Is there a missing PCATCH flag to tsleep() somewhere?
Is this appropriate behavior? (hint: rhetorical question)
Just Curious,
-Archie
