Well, it is one option to extend mod_rewrite. What I meant
specifically was that any module can implement a rewritemap internal
function.
Yes, the feature seems to be a bit too specific for general
implementation in mod_rewrite.
Ben: have a look at how mod_rewrite accesses its own
ap_register_rewrite_mapfunc via
map_pfn_register = APR_RETRIEVE_OPTIONAL_FN(ap_register_rewrite_mapfunc);
Any module can access the function using this construct. And then
mod_rewrite registers builtin rewrite map functions e.g. like
map_pfn_register("escape", rewrite_mapfunc_escape);
Your own module can also register your own functions like myuid and mygid:
map_pfn_register("escape", my_mapfunc_uid);
Then you can configure a RewriteMap to use these functions and they will
call directly the my_mapfunc_uid function in your module to get the uid
without the need of an external process with locking etc.
In short: the list of builtin functions for RewriteMap is extensible and
can be extended by 3rd-arty modules using the above method.
If uid and gid alone isn't powerful enough, you can code whatever logic
you need in your map function and register it with a name that is
reasonable for you and doesn't clash with what's already there in
mod_rewrite.

I can't think of any solution that would work out of the box, but
you can always write your own apache module in C.
Which could provide nothing but a new internal rewritemap type.
Rainer, Eric,
Thank you very much for your feedback.
Yes a new rewritemap seems to be the solution.
type name : usr
functions : uid, gid
parameter : name or #uid
For example :
RewriteMap getuid usr:uid
RewriteMap getgid usr:gid
C functions getpwnam and getpwuid would do the job.
Is a pull request here the right method to proceed ?

Thank you very much,
Ben
