michael@0:  * Description: a test for Bugzilla bug #17699.  We perform
michael@0:  * the same test for PR_Writev, PR_Write, and PR_Send.  In
michael@0:  * each test the server thread first fills up the connection
michael@0:  * to the client so that the next write operation will fail
michael@0:  * with EAGAIN.  Then it calls PR_Writev, PR_Write, or PR_Send
michael@0:  * with a zero-length buffer.  The client thread initially
michael@0:  * does not read so that the connection can be filled up.
michael@0:  * Then it empties the connection so that the server thread's
michael@0:  * PR_Writev, PR_Write, or PR_Send call can succeed.
michael@0:  *
michael@0:  * Bug #17699 is specific to the pthreads version on Unix,
michael@0:  * so on other platforms this test does nothing.
