One more data point to add, I've been looking at an identical issue when
copying large amounts of data. I bisected this - and the lockups occur
with commit
3e7d344970673c5334cf7b5bb27c8c0942b06126 - before that I don't see the
issue. With this commit, my file copy test locks up after ~8-10
iterations, before this commit I can copy > 100 times and don't see the
lockup.
