udev: lower the starting children_max -> drop the minimum required RAM from 23mb to 5mb
Udev was the limiting factor for us on low-RAM systems. Given an average RSS of 180kb, 128 workers would require ~23mb of RAM. Now, please consider what happens when there is only, say, 15mb free. Udev protects itself from OOM, and the kernel can do nothing but panic. 28 workers * 0.18mb = ~5mb. This change should not affect more powerful systems much, given that they still get the addition from the amount of RAM.
