LaunchBar + FUSE slowdown
Lockup only occurs when:
- KBFS is active (any fuse fs would likely do the same)
- There are applications within the search results
- You use the keyboard up or down arrow to move _away_ from an application (doesn't matter what you are moving to, what you are moving from)
LaunchBar is configued to not scan KBFS for applications, not index as part of mounted volumes.
If you use a mouse to change item, then it doesn't lock up (select application, select something else)
If there are no applications in the list, then it doesn't lock up
The lock up occurs for ~15-20 seconds
