Alex Shinn	8b5eb68238	File descriptors maintain a reference count of ports open on them ... They can be close()d explicitly with close-file-descriptor, and will close() on gc, but only explicitly closing the last port on them will close the fileno. Notably needed for network sockets where we open separate input and output ports on the same socket.	2014-02-20 22:32:50 +09:00
