Recent changes to 40: Allow multiple instances to read from the same image

#40 Allow multiple instances to read from the same image

Unfortunately, I have to put a lock on it otherwise Windows will be updating the filesystem as I am trying to read from the raw device (and Windows won't allow that). It would be like trying to read a file as you are formatting the media the file is sitting on.

This is more of a Windows limitation, not an app limitation.

yes you should remove the file lock, my computers has 4 usb ports and I can only write with one at a time, what a waste

As an easier way to support writing to multiple targets at the same time (feature 32), how about allowing multiple instances of Win32DiskImager to read from the same file? Right now it seems to lock the file for exclusive reads so two instances can't write the same file to two different drives. I only need to write to two USB drives at a time so a fancier solution isn't needed for my use case.
