      Description

        Currently the 'generic' hs_errfile Events message log (filled by Events::log) is sometimes rather full by messages for memory protection operations and nmethod flushes. Those seem to occur quite often and potentially move out other less frequent events, because the number of entries in the log is limited.
        It might be better to separate those events into separate sections.

        memory protection operations related entries look like this :
        Event: 0.178 Protecting memory [0x000000016ebf0000,0x000000016ebfc000] with protection modes 0
