I'd suggest:

"Registers native method hooks with the Java runtime specified by |env|. Returns
false if registration fails, in which case native methods are unavailable to
Java."

It wasn't clear to me reading the code whether the hooks actually retain
references to |env| or whether this method is self-contained?

Ah yeah it's self contained (at least as far as our automatically generated JNI
code is concerned).

+bool RegisterBlimpJni(JNIEnv* env);
