Tuxonice + BFS?

Hi,

Out of interest, I've tried to get tuxonice and Con Kolivas' BFS patch 
running (linux-3.1-rc2). As long as compression is not used, everything 
works fine. As soon as I turn on compression (lzo or lzf), I get some 
errors -22 on resuming (or some byte count mismatch with lzf).

I can get tuxonice + compression + bfs to work correctly when I revert 
the following two commits (and leave no_flusher_thread = 1):

3eaa98fda1f9d6727ab2862bf83c9bcfd8c83789: Fix progress update with 
flusher thread.
c2a116d1236344e6ce2556bbc674489ee5d2f703: Start/stop I/O worker threads 
outside of freezer

Actually, it's c2a116d which causes the problem. I think the commit 
should fix the hangs when using no_flusher_thread=0?

Any idea what's going on here? Why does this cause problems with BFS but 
work fine with the default kernel scheduler?
