Currently there's no way to prevent the huge size of binarylogs which are generated in a short period of time. In our case we use binlog for MASTER-SLAVE replication and a high traffic weekend filled up the diskspace in the master server.
Percona has implemented max_binlog_files directive which can be used to ensure the maximum disk usage of binarylogs with conjunction with max_binlog_size directive.
I do not know if this is relevant but the author mentions some drawbacks using max_binlog_files variable and suggest a variable max_binlog_space or binlog_space_limit instead.

This would be a useful option! Be it max_binlog_files or binlog_space_limit.
We have a 130GB DB replicated to a backup cluster, and binlog consume about 400GB of HD for a single day!
