Yes, I know this FAQ.

I've deleted around 40 GB files, but still occasionally see "No space 
left on device" when removing files, or when copying new files to btrfs 
filesystem (i.e. copying one file fails with "No space left on the 
device", while there is ~70 GB free on btrfs filesystem; and copying 
some other files, with similar or bigger size, succeeds).
