Cygwin supports Windows ACLs as POSIX ACLs, which are also supported by Linux.
Use setfacl to set similar default ACLs (DACLs) on a Linux directory, rerun your
test there, and you should see similar results.

*Never* remove DACLs from any Windows directory which will *ever* be used with
any non-Cygwin Windows program: /undefined behaviour/ will result.
Mostly neither Cygwin nor Windows programs will be able to do anything with
those files until you fix the permissions problems using elevated commands ;^>
