yes, but you can use forkOS from Control.Concurrent and compile with
-threaded.
See the relevant documentation for the details.
forkOS not relevant here.
-threaded is necessary to allow haskell code to run whilst FFI calls are
blocked. getChar doesn't count as an FFI call (the RTS does its own IO
multiplexing) but system does.
forkOS is to do with bound threads, that's something else.
