Errgh, I really don't like this.
Checking if package foo is running before upgrading it, yes.
Checking if cygwin is running at all, no.

Which doesn't cover all cases :p. (Ie cygwin1.dll is only one file to be
detected for write issues.)

What we need is to be able to check for any of the .exe's or .dll's in a
package, before uninstalling, and allow a [cancel][retry] option. You're
right that the snapshot approach is probably best.
