    Do anyone know why mask is used here?


I thought QSem was known to be completely unsafe and
http://hackage.haskell.org/package/SafeSemaphore was recommended
instead, with QSem and friends slated for removal?

FUD! :)

I revamped it for 7.6 rather than remove it, it's safe and fast now.

In any case, there are probably leftover attempts to make it safe, yes.
