* New asynchronous exception control API (base parts)
As discussed on the libraries/haskell-cafe mailing lists
http://www.haskell.org/pipermail/libraries/2010-April/013420.html
This is a replacement for block/unblock in the asychronous exceptions
API to fix a problem whereby a function could unblock asynchronous
exceptions even if called within a blocked context.
The new terminology is "mask" rather than "block" (to avoid confusion
due to overloaded meanings of the latter).
The following is the new API; the old API is deprecated but still
available for the time being.
Control.Exception
-----------------
mask :: ((forall a. IO a -> IO a) -> IO b) -> IO b
mask_ :: IO a -> IO a
uninterruptibleMask :: ((forall a. IO a -> IO a) -> IO b) -> IO b
uninterruptibleMask_ :: IO a -> IO
getMaskingState :: IO MaskingState
data MaskingState
= Unmasked
| MaskedInterruptible
| MaskedUninterruptible
Control.Concurrent
