We should probably have `RemoveIn` as well: ```go // RemoveIn removes the named file or (empty) directory. // It applies the same constraints on files as [OpenFileIn]. // It otherwise...

Updated proposal, with comments on various changes arising from above discussion and working on implementation. The `OpenFileIn`, `CreateIn`, and `OpenIn` functions are unchanged from the original proposal: ```go package os...

The fact that `synctest` goroutine groups always use a fake clock will hopefully act as discouragement to using them in non-test code. Defining goroutines blocked on I/O as not being...

One of the goals of this proposal is to minimize the amount of unnatural code required to make a system testable. Mock time implementations require replacing calls to idiomatic time...

I wanted to evaluate practical usage of the proposed API. I wrote a version of Run and Wait based on parsing the output of runtime.Stack. Wait calls runtime.Gosched in a...
