If a failed commit is cleanly aborted (which Subversion attempts to do when
possible), then all the data associated with the transaction should be
purged from the back-ends. Sometimes commits aren't cleanly aborted,
though, and Subversion doesn't try to guess which commit transactions are
stale versus maybe just long-lived because the client connections are
unnaturally slow. This is why we provide administrators with the 'svnadmin
lstxns' and 'svnadmin rmtxns' subcommands.

(By the way, this question belongs on the users@ list, as it has nothing to
do with discussing the development of Subversion itself.)
