Indeed, but think that's another reason to move the freeing to
xlog_recover_process_data. Right now or with the proposed patch
xlog_recover_commit_trans frees trans, but there's nothing that
breaks out of the loop in xlog_recover_process_data after that case.
By moving the freeing there for all cases we can add a corruption
check for that case, and we have a single function that controls
the lifetime of the xlog_recover structure.
I like that idea of doing the frees in xlog_recover_process_data().
Each loop allocates a new trans, so each loop is self contained.
