Windows is not Linux, and will not allow users to delete in-use
directories (where a directory is considered in-use if it contains files,
or if any process is using that directory as its current working
directory), nor the clean deletion of files that are still open. POSIX
allows this behavior, and cygwin cannot change Window's implementation of
deletion semantics. Just because Linux behaves nicer doesn't mean that it
is portable to remove in-use directories. Fix your code to first close
all outstanding file handles before trying to remove the files, and then
the directory.
That said, cygwin does try to emulate linux, and if someone were to
contribute a patch that would allow cygwin to emulate directory deletion
if it knows that all open handles have also been scheduled for unlinking
at process end, then http://cygwin.com/acronyms/#PTC.

pseudocode like this is worthless when asking for help. Post a simple,
self-contained, compiling testcase if you want more help.
