[TxMt] [TM2] Files on remote mounts not being refreshed - workaround?

When I open a file on a local HFS+ drive in TextMate2, it will pick up changes to the file if I edit it with another tool, or alter it at the command line.

This does not happen through files opened via rmate, or through files opened on SMB shares mounted on the local machine. I assume that there simply is no file-changed event to listen for in this case, but it would be nice if I'm wrong.

As a workaround, is there a simple way to trigger a refresh of the TextMate buffer? Since I have control of both the save within TextMate and (in this case) CVS update cycle, I can ensure a consistent state that way.
