Yes, the content of both files is read into memory.  Cygwin needs the
information, especially name, u/gid and SID.

It doesn't count as a bug but it's a well known problem since... well...
3 years or so.  It's way faster than it was back then but we still don't
have an optimal solution.

Workaround:  Don't use such big files.
