+Subject: [PATCH 1/4] tests: F_SETFL does not return flags, use F_GETFL again
+
+Fix TestGreenSocket.test_skip_nonblocking() to call F_GETFL again
+to get the flags for the socket.  Previously, the code wrongly assumed
+F_SETFL will return flags while it always returns 0 (see fcntl(2)).

+Subject: [PATCH 2/4] tests: Unset O_NONBLOCK|O_NDELAY to fix SPARC
+
+Fix TestGreenSocket.test_skip_nonblocking() to unset both O_NONBLOCK
+and O_NDELAY.  This is necessary to fix tests on SPARC where both flags
+are used simultaneously, and unsetting one is ineffective (flags remain
+the same).  This should not affect other platforms where O_NDELAY
+is an alias for O_NONBLOCK.

+Subject: [PATCH 3/4] tests: Assume that nonblocking mode might set O_NDELAY to
+ fix SPARC
+
+Fix test_set_nonblocking() to account for the alternative possible
+outcome that enabling non-blocking mode can set both O_NONBLOCK
+and O_NDELAY as it does on SPARC.  Note that O_NDELAY may be a superset
+of O_NONBLOCK, so we can't just filter it out of new_flags.

+Subject: [PATCH 4/4] tests: Increase timeout for
+ test_isolate_from_socket_default_timeout
+
+Increase the timeout used for test_isolate_from_socket_default_timeout
+from 1 second to 5 seconds.  Otherwise, the test can't succeed
+on hardware where Python runs slower.  In particular, on our SPARC box
+importing greenlet modules takes almost 2 seconds, so the test program
+does not even start properly.
+
+Fixes #614
