Not all filesystems are local. Cancellation is very much possible for NFS (for which I'm actually already using a Go-based client).

By cancellation in this context, do you mean timeouts/deadlines? Or actually being able to cancel a read/write at any given time? If it's timeouts, does it work to specify a read/write timeout when you open the filesystem client (or Open() a file), rather than for example having a ctx/timeout on every Read call? Similar to what Russ Cox asks here: https://www.reddit.com/r/golang/comments/hv976o/qa_iofs_d...

By cancelable in my initial response I meant ability to interrupt a given blocked call so it returns immediately. Timeouts are a subset of that.

What would be ideal if FileHandle can be used as a pseudo-channel in the select statements in Go. But that requires very non-trivial implementation especially on Linux.
