* Try to figure out how deep we can go in our tests. Assumes that

* limits in our Win32 support.
*
* Background: On Posix systems, PATH_MAX is merely a limit on the
* length of the string passed into a system call. By repeatedly
* calling chdir(), you can work with arbitrarily long paths on such
* systems. In contrast, Win32 APIs apply PATH_MAX limits to the full
* absolute path, so the permissible length of a system call argument
* varies with the cwd. Some APIs actually enforce limits
* significantly less than PATH_MAX to ensure that you can create
* files within the current working directory. The Win32 limits also
* apply to Cygwin before 1.7.
*
* Someday, I want to convert the Win32 support to use newer
* wide-character paths with '\\?\' prefix, which has a 32k PATH_MAX
* instead of the rather anemic 260 character limit of the older
* system calls. Then we can drop this mess (unless we want to
