[erlang-questions] dirty_update_counters and mnesia_frag

[Evgeny M]

Follow up:
I copied key_to_frag_name and its' dependencies from mnesia_frag.erl to my 
project. Now I generate frag table names in my code and 
use dirty_update_counters on a generated table name, bypassing mnesia_frag 
callback altogether. I use this for dirty_update_counters only and call 
mnesia:activity(..., mnesia_frag) for everything else, like selects etc. 
Could there be any problems in such workflow? There are no other write 
operations besides dirty_update_counters and clear_table.
