Is this block-channel makes goroutine synchronized?
Is this a better way?
children_quits := make(chan bool, len(urls))
for _, url := range urls {
go RCrawl(url, depth-1, fetcher, children_quits)
}
for i := 0; i < len(urls); i++ {
<-children_quits
}

Line 50 in f28113e
for _, childrenUrl := range urls {
go CrawlRecursive(childrenUrl, depth-1, fetcher, childrenQuit, visitedUrls)
// To exit goroutines. This channel will always be filled
<-childrenQuit
}
This loop is not executing in parallel. Only one crawlRecursive will be called and other has to wait due to <-childrenQuit.
So it seems like code is executing sequentially rather than parallel.
Let me know if you think otherwise.
