// Package main implements streaming of a file through a buffered channel where it is written to a new file.
// A data race condition arose in the for loop that reads data from the input file and sending it to the channel.  
// I moved the allocation of the buffer to the top of the loop, to resolve the data race issue.  
// I've created a companion gist,"go-stream-file-between-goroutines-with-pipe" that resolves the race issue using a 
// FIFO pipe.  It worked, but the price was that it was slower than using a channel.
