Tyler Hobbs commented on CASSANDRA-10779:
-----------------------------------------

Since {{Striped}} actually uses {{ReentrantLocks}}, it turns out a blocking 
solution works for my purposes.  I've pushed a second branch with blocking lock 
acquisition.  As discussed, it uses {{bulkGet()}} to ensure lock acquisition 
order is consistent (avoiding deadlock):
