These are UI requirements.

When an MMC is inserted, there's a banner about that "immediately"
(after it's mounted).  If you have Mediaplayer open, it has a progress
banner about "Refreshing library", so both of the requirements should
actually be met.

The latest release has a fix to (open source) libid3 which made
crawler to spend upto 1min on some specific mp3 files (libid3 scanned
the whole file if it didn't find any metadata).  This should've fixed
the most glaring issue with crawler.

Next release should fix rest of the issues crawler has
with corrupted MMC (and symlinks):
- infinitely recursing directories
- directories with infinite number of items (looping contents)
(as can be seen from bugzilla)
