[Haskell-cafe] GHCJS/Firefox support for forkIO and MVars

It is just what GHCJS needs for threading support (at least in Firefox).
Here is what I did to get it working in GHCJS...
* Added "Jump" so that tail calls don't grow the stack
* Implemented a really basic scheduler
* Added some thread and MVar primitives
* Added a YieldTrampoline calling convention to GHCJS
The code is here https://github.com/hamishmack/ghcjs
cabal install
cd examples
runhaskell BuildTestYield.hs ../../ghc-7.0.2
Then open test-yield.html in Firefox.
I think you can build it with any GHC 7 (I used 7.0.3), but you need the 7.0.2 source. I get this error when I try to use the 7.0.3 source...
../../ghc-7.0.3/libraries/base/GHC/Unicode.hs:35:0:
error: HsBaseConfig.h: No such file or directory
