Raghu Angadi commented on HADOOP-5116:
--------------------------------------
hmm... did you try strace (or its AIX equivalent) on the busy thread? On Linux,
I find the pid of the thread doing write() with jstack.
This test depends on the fact that a pipe has a reasonably finite buffer. So
when it writes to the pipe in a loop, it expects write to return 0 at some
point and polling for 'POLLOUT' would timeout after that since there is no
reader on the other side.
