Interrupting GHC August 27, 2010
In my tech talk about abcBridge, one of the “unsolved” problems I had with making FFI code usable as ordinary Haskell code was interrupt handling. Here I describe an experimental solution involving a change to the GHC runtime system as suggested by Simon Marlow. The introductory section may be interesting to practitioners looking for working examples of code that catches signals; the later section is a proof of concept that I hope will turn into a fully fleshed out patch. :
