Sorry I start spin-off of thread but all over the haskell code is idiom:
throwErrorIfMinus1_ $ someCode args
However this code is dependent on errno, which is thread dependent. Is
GHC making sure that errno set from C call is propagated back into

Yes, it is.
Are there any requirements regarding safeness/unsafeness of such

No there aren't.
Cheers,
