Primary.  The way most other UNIXen of the world do it.

I would certianly not change a default behavior, but I'd still like to see
the option of using the user's primary gid when creating a file if BOTH of
the following conditions are false:

- the directory is setgid or sticky
- the user has the directory's group ID in the user's group list

If either of these two conditions are true, using the directory's group ID
is fine with me.  I'm more concerned about files having a group ID other
than a user's allowed group IDs; on SVR4, that is just plain not possible.
