What did you do?
If possible, provide a recipe for reproducing the error.
A complete runnable program is good.
A link on play.golang.org is best.
From the Windows command line (CMD), I used go run to run a hello world program like https://play.golang.org/p/v3rrZLwEUC
go run hello.go
What did you expect to see?
I expected the program to return to the command line immediately.
What did you see instead?
The program hung for a few minutes after it appeared to be done (e.g. after the last output was written).
And, it could not be interrupted with Control-C.
Note that the problem (delay) does not seem to occur with a compiled version of the program, just with go run.
