Hello, I would appreciate if those of you with portage development experience and a moment to spare could please take a look at:

https://github.com/gmt/gmt-cygwin-overlay/blob/master/sys-apps/portage/files/portage-2.2.01.20271-cygdll_protect.patch

Not gunning for upstream or anything, but I would eventually like to start moving towards "not a complete pile of crap" status :)

Notes:

  o based against a-few-weeks-old rsync prefix-portage

  o may contain a very few hunks that should arguably go
    upstream--I will make bugs for them and they are not
    what (I feel) needs eyeballs.

  o trying to actually run this may be difficult.  let me
    know where you're stuck and I'll try to help.

  o I must admit, I pretty much learned python as I went,
    so... if you are thinking "that looks like a total
    rookie mistake" it probably is, and I'd probably
    appreciate your constructive critique.

  o I'll probably keep hacking on this so... moving target.
    But it's mostly working, I think.

  o This doesn't make any big changes to upstream code.  So,
    If it looks like it might be a big indentation change,
    it probably is.

  o this is to solve the problem that, in cygwin, a running python
    crashes as soon as you change any filesystem .dll's on which
    it depends and fork() -- this is semi-orthogonal to the
    typical cygwin "rebasing" problem and distinct from it.
    The problem has nothing to do with locked files (except
    that my solution does use some standard portage file-
    locking features).
