Yes you're right. Looking in the glibc sources
setfsuid aren't caught by the SETXID wrappers,
so they'll be thread specific on Linux.
What I'm thinking of is adding checks for
and use them by preference inside smbd to
restore the semantics we were depending on,
(they'll fit inside source3/lib/util_sec.c)
and also use them inside worker functions
called from a threadpool to set the credentials
correctly for the IO operation.
