I will dig to the history.
With my current patch may be having a hash table of 'txn id'(char*) Vs
'mergeinfo(apr_hash_t*) at the fsap_data should take care of the
multiple transaction issue too, as each txn will have its own 'id'.

Will evaluate the history and try the above thing and post back to the list.
