Unable to get temp file on Windows

[kerbo]

This issue was introduced in 9.0.3.0. When trying to upload a file, I get this error from Rack Multipart upload:

Unable to find a non world-writable directory for Dir::tmpdir. Consider setting ENV['TMPDIR'], ENV['TMP'] or ENV['TEMP'] to a non world-writable directory.

I reverted back to 9.0.1.0 and everything is working again.

I get this when trying to run rails console, so can't even initialize Rails on 9.0.3.0

Environment:

Hmmm I wonder if this is the fstat bug we introduced, @enebo.

@headius Is the fstat bug what's causing this when I try to run jirb with 9.0.3.0?
