Comment (by dd32):

 > Looks like this is only happening because the test in question is
 realpath()ing the result.

 That sounds like something that someone would do to work around symlinks
 or something.

 I'll also note this here, I am somewhat unconvinced that we *actually*
 need to use `win_is_writable()` at all in core, however, I'm unsure of the
 latest PHP version which is affected by the bugs which require it's use (I
 would not be surprised if PHP 5.2 is affected, while 5.3/5.4 are not).

 Since this change means that a system directory outside of the normal web
 directories may be used, I thought it was the safest bet to use
 `win_is_writable()` to prevent any edge cases.  A new ticket will need to
 circle back on it, but I'd really like to define the conditions which make
 it needed.
