Potential memory leak in BloomFilterWrapper

[s3cur3]

The BloomFilterWrapper doesn't clean up the BloomFilter it allocates on init. As best I can tell, this is mostly a theoretical leak—in the app, the BloomFilterWrapper is currently retained for the lifetime of the program. If this ever were not the case though (as is the case in the test suite), the allocated BloomFilter would be leaked.

If you'd like, I can submit a pull request for the (tiny) fix.

Sorry for the delay in replying. Yes, feel free to submit a PR. As you say the filter is tied to the the lifetime of the app anyway so no rush. Thanks!
