Looks good, can you re-build and commit the updated files?

was the intent of adding run-command to allow passing params in webworkers? if so can we close this as duplicate of #364?

also is run-command concurrency-safe? i did try hacking run-command into workers in the past, and got weird results when posting multiple-messages concurrently. it could've been programming error on my part, but i've stuck to exec since that experience.

You can see the commit here. It was not a duplicate of #230

I'm not sure exactly what you are referring to by run-command.
When you use a webworker, the messages you send are still handled sequentially on a single thread. There is no problem with sending a new message before receiving a response for an old one.

ok run-directive has different intent and is concurrency-safe. @Airsola, if you still want to contribute, you can submit a new pull-request in vanilla js.

feel free to use commit 632effa as reference, as the feature-set is somewhat similar, including testcase
