I believe the OS threads are created by my levmar library. This library uses bindings-levmar[4] which is a binding to a C library. bindings-levmar uses safe FFI calls because the levmar C procedures are reentrant (they need to call back into Haskell to execute the model function). I believe the RTS creates an OS thread for each safe FFI call.
Sounds like #4262: http://hackage.haskell.org/trac/ghc/ticket/4262
(Should be fixed in head)
That looks exactly like my problem. I will try it out with ghc head on monday. Thanks! Bas
