Invalid request code when removing files

[David Macek]

I would ask about your Cygwin and Windows versions, but unless you're
running an Insiders build, I don't think WSL is supposed to be this
broken. Are you by any chance running a third-party antivirus or
security suite or some uncommon driver, file system software? Consult
the BLODA<https://cygwin.com/faq/faq.html#faq.using.bloda> for the
worst offenders, but note that this list is not exhaustive.
