Go doesn't have a general abstraction for that either. If you put something in a goroutine, you usually cannot cancel it. If you decide to timeout, the goroutine will continue to run. This may not be important for an mkdir(), but this may be for other stuff, like for example for accepting a connection. The not-cancelled goroutine will have an important side-effect on your program (stealing a connection). Moreover, Go wrapper functions automatically restart a syscall when it is interrupted. Therefore, you cannot cancel a syscall by sending yourself a signal. This may change in the future when everything will take a context (at the cost of an API change), but this is currently not the case.
