Just to be absolutely sure... Does the above apply to safe _and_ unsafe FFI?
I have been using the non-threaded runtime with unsafe FFI calls (OpenSSL, Zlib) and I do not believe my runtime was being blocked. Maybe I just didn't notice it, though.
Maybe this little table will help: Do other Haskell threads get blocked during an FFI call? | safe unsafe --------------+---------------- -threaded | NO YES no -threaded | YES YES Cheers, Simon
