[Haskell-cafe] Unbound threads and FFI

[Simon Peyton-Jones]

Did you read the paper Extending the Haskell Foreign Function Interface
with Concurrency, described in the GHC Wiki page about concurrency?
It'd be a good start
http://hackage.haskell.org/trac/ghc/wiki/GhcConcurrency

Please do improve it.

Simon

| 
| How do unbound threads play with FFI? According to Simon PJ, each
| foreign call will get its own OS thread if its blocked.
| 
| How does GHC determine if the call is blocked? Does each call get its
| own OS thread from the start? Sometime later? Does this depend on the
| safe/unsafe specs of the foreign call?
| 
| Does the above change if a threaded/non-threaded runtime is in use?

| 	Thanks, Joel
