It's a common hurdle that new users of the CycloneDDS RMW find their topic subscribers grinding to a halt once they plug in, for example, a couple Intel RealSense RGBD cameras - or even a simulated equivalent in something like Gazebo.
For reasons discussed in #511, it's not practical to ship the needed configuration change within this package - so we should log a warning if we detect an rmem_max that's unlikely to result in a good experience.
Implementation considerations
Some part of the RMW will need to check what the kernel's current rmem_max is and emit a warning if it's below a certain reasonable threshold. Perhaps the value specified in the CycloneDDS tuning guide?
