Note that opera has "opera:libflashp" in /proc/self/comm which would be
a bit easier to check.

However, konqueror (nspluginviewer) doesn't have anything recognizable
in either /proc/self/cmdline ("/usr/bin/nspluginviewer -dbusservice
org.kde.nspluginviewer-15523") or /proc/self/comm ("nspluginviewer"), so
for that we do need the /proc/self/maps check.

So I'm not opposed to checking /proc/self/maps for opera as well as we
can then use exactly the same code for konqueror as well, this is just a
BTW :)
