This has bothered me several times, too. If the user's umask is
set wrong, other's won't be able to change his installations.
It can both be seen as a bug or a feature though.

Today we leave all the permission settings to the OS. At least on
POSIX the builder could set the group bit or just apply its own
umask (defined in cm3.cfg). I don't know what to do on Windows,
though; and on POSIX systems ACLs are used more and more.

What do other's think: do we want to add some support for permissions
wrt. team working?
