Deadlock when copying to a FAT32 volume #34

My wife asked me to transfer her photos from the backup location on my server to her usb thumb drive. In order than she can mount this drive on Windows I have it formatted as FAT32. I thought I'd give fcp a go to speed up the transfer since it usually takes a very long time with rsync or cp. While the transfer did begin at an amazing speed, it eventually deadlocks waiting for a FUTEX that apparently never gets released. I was able to determine this by stracing the process.

I attempted this several times to see if it was a fluke and it deadlocked every time after transfering about 8-10G of data
