Subject: [PATCH] Fix FileIOThread concurrency issues
FileIOThread was using two volatile counters in order to track if
any pending work was in the queue, this causes potential concurrency
issues when this counter is updated from multiple threads, potentially
causing these counters to desync due to the unsafe volatile update
