Here is the backtrace:

thread 2 is waiting on the same lock held by thread 1.
The setup was a simple protocol/client and protocol/server setup with stat-prefetch loaded on it. I was debugging some bug (ls on mount point used to hang) in stat-prefetch when I hit this bug. The operation being done was ls on mount point.
