commit 925f7e4c35fb335b3f57000371592db9f2206766
Author: Peter Amstutz <pamstutz at veritasgenetics.com>

    14458: Avoid panic by removing defer close()
    
    Channels will be garbage collected when they go unreferenced.
    
    Make the errors channel buffered to avoid lingering goroutines trying
    to send on an unbuffered error channel with no reciever.
