Comment:

 #1592 looks related and I think I understanding the reasoning (the earlier
 `hs_lock` call might exit the program and hence the argument won't be
 used). I'm fine with this behavior but it'd be nice if I was able to tell
 the compiler that the function is strict. Adding bang patterns on the
 arguments has no effect at all.
