Wouldn't it be preferable to have the Delay interface not depend on java.util.concurrent.TimeUnit?

That plan for js port of kotlinx.coroutines is to define `typealias TimeUnit=java.util.concurrent.TimeUnit` on JVM and have it implemented on JS via enum.

shouldnt tha change of signature on JVM be done as soon as possible

so that a later introduction for JS doesn't require a breaking change on the JVM

I mean, this type alias could be put in place right now (i.e. 0.15)

~wait, i guess the typealias needs to go into stdlib, not coroutine lib, right?~
~then please ignore my reference to 0.15 :slightly_smiling_face:~
To understand that right, will there be different kotlinx-coroutines-core libraries for JVM and JS? Or do you mean stdlib will get a TimeUnit typealias?

First. Different core lib for JVM and JS. 

Maybe stblib will get this typealias in the future, too. 

Great. If the type def goes to the core lib, you could provide it soon without breaking anything but enabling people to write more future-proof code. You get my vote on this :slightly_smiling_face:
