It's a long shot, but in addition to Chris's excellent suggestions, try 
the skip_balance mount option.  In the outside case that it's just a 
resumed balance that's triggering the hang, that should allow the rw 
mount to succeed as it kills the balance that would otherwise be 
immediately resumed as soon as the filesystem goes writable, possibly 
before the mount returns.

Otherwise, I'd go with Chris's suggestion, mount read-only and ensure 
your backups are current, then go experimental on it, since there's 
nothing further to lose at that point anyway.
