Known limitation in dash - it is going off of just st_mode bits instead
of using faccessat() and honoring ACLs.
My guess is that if you do 'getfacl /Users/tmcdaniel/AppData/Local/Temp'
and 'id', you will find that your current uid and gid are not the owner
of the directory, but do have an ACL granting write access to the
directory anyway.
I've been meaning to do a new build of dash (aka ash), and to force the
use of faccessat as part of that build; I just haven't had the time to
get to it yet.
