I don't think so (I wrote the kernel code that results in that message). It's a probabilistic thing in the kernel, dependent on how much I/O is going on at the time, with a 3 second timeout.
I suspect the player issues the unmask command at the same time that lots of other disk I/O is happening, and sometimes it just doesn't get done within the three second allowance.
(note that there's been a "fixme" note on that code since the beginning, but nobody's ever gone back and fixed it).
I'll increase the timeout to 6 seconds in the next Hijack kernel.
Cheers
