Solution explorer doesn't refresh after renaming a file

[huguesv]

If you rename an existing file in solution explorer, the file on disk gets renamed, but the tree node is unchanged. The icon shows the file as missing.

Note that this doesn't happen for a fresh instance of VS. I haven't found what the trigger is yet. But working in a project that's been opened for a long time, every rename I'm doing fails to refresh as described above.

I vaguely remember from PTVS/NTVS that file system watchers have a tendency to stop working after a while (too many events?) and that may be the case here.

Edit: A project that I opened 20 mins ago is now reproducing the issue, and I haven't made much changes to it at all. It may just be a matter of leaving it open for a while.
