Maybe there should be some function like maskUninterruptibleExceptUser
which would mask everything except UserInterrupt exception. Or maybe
UserInterrupt

That helped, thanks!

I bet, if you switch off the barrage of thread scheduling SIGALRMs,

Hello,
the following program should wait 3 seconds for user input before. If
now user input occurs within that time, it just prints -1.
{-# LANGUAGE ForeignFunctionInterface #-}
module Main where
import Foreign
import Foreign.C.String
import Foreign.C.Types
import Foreign
Relatedly, it seems that it takes a nontrivial amount of time for
the multithreaded RTS to "realize" that a thread has emitted a
signal. I wonder if there's a more direct way an FFI call can say
"when I get back to Haskell, immediately start propagating an exception."

Hi John,
I'll take a look at trac #2965. You should be able to build the
7.0.1-rc2 tarball
simply by unpacking it and following the instructions in the README.
(In short,
configure, make then make install ought to work.)
If it doesn't build properly out of the box, I'd be interested in

I can try building 7.0.1-RC using a 32-bit 6.12.3, although probably not
until the weekend. I'll let yo
