Alex Shinn	fe80e56db9	Exporting file-link-status. Fixing a bug in directory-fold-tree, ... down should be called exactly once per directory with a matching up.	2014-03-09 20:09:06 +09:00
Alex Shinn	8b5eb68238	File descriptors maintain a reference count of ports open on them ...

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
