Not a Windows or Perl person, but I see that you can redefine core
functions with *CORE::GLOBAL::open = <replacement/wrapper>, if you
wanted to make a version of open() that does that FILE_SHARE_READ
dance.  Alternatively we could of course have our own xxx_open()
function and use that everywhere, but that might be more distracting.

I'm a bit surprised that there doesn't seem to be a global switch
thing you can set somewhere to make it do that anyway.  Doesn't
everyone eventually figure out that all files really want to be
shared?
