1017	socket-receive blocks for connectionless sockets	Jim Ursetto	Jim Ursetto	"klm identified a bug in the socket egg; nonblocking mode is only set during a socket-connect or socket-accept, which won't be called for UDP.  Test case attached.

Temporary workaround: (use posix) and then, after creating the socket, do either:

(##sys#file-nonblocking! (socket-fileno *socket*))

or equivalently

(file-control fcntl/setfl (socket-fileno *socket*)
 (bitwise-ior (file-control fcntl/getfl (socket-fileno *socket*))
              open/nonblock))

Neither workaround will work on Windows.

Permanent fix: We should probably make all sockets nonblocking at creation time instead, since our machinery assumes nonblocking sockets.  We could expose the set-nonblocking operation to the user, but since TCP is always nonblocking, doing this only for UDP would be strange.
