Alan Donovan 3a85b8da38 refactor/importgraph: reduce I/O concurrency to avoid EMFILE ... Use an concurrency-limiting semaphore to reduce I/O parallelism in Import. Also, start the producer in a new goroutine so that it runs in parallel with the consumer. Paradoxically, this reduces the peak number of goroutines. Also, in buildutil.ForEachPackage, make the concurrency limiting semaphore global, since I/O parallelism is a process-wide resource.
