Joshua McKenzie commented on CASSANDRA-7316:
--------------------------------------------

Philip and I discussed this online briefly - looks like the currently attached patch doesn't
handle swap files on drives other than C:\  I'll dig into it a bit and see if I can't make
it a bit smarter and check other volumes.

> Similar to mlockall() in CLibrary.java for linux, it would be nice to lock the virtual
address space on Windows to prevent page faults.
