Hello Alistair,

they don't to it directly. but without -threaded +RTS -N (or forkOS)
there is only 1 OS thread that runs all haskell threads. unsafe call
blocks it untill call finished, while safe call allows to reuse it for
other haskell threads execution. i've attached old ghc commentary on
this topic, although things may be significantly changed ATM

Best regards,
