>Description:
Compile this test case:

http://cvs.apache.org/~jorton/nonblock.c

the program reports on NetBSD that O_NONBLOCK is not inherited across accept(), which does not appear to be the case.  If you add a read() from the accepted socket, it will fail with EAGAIN.

fcntl(, F_GETFL) appears to be lying about the socket flags.
