Oh right, I thought it wasn't.

Well for schema update I need process A to tell process B I have 
reloaded the schema because I had too or I was asked so should you.
I was suggested to use tdb_inc_seqnum and tdb_get_seqnum as I don't need 
to have an exact value but just the info that something has changed and 
that schema has to be reloaded.
So it wouldn't be too bad to be able to use tdb_inc_seqnum (ldb seems to 
call it directly).
