2013-11-08 Thread sven
From: Sven Eckelmann A small system like the common home router doesn't have 40 MiB per process for a dirty stack cache. This can easily lead to an overbooking OOM problem and caused a lot of hangs+reboots on 32 MiB systems running nodogsplash. Not using a stack cache can increase the time to sp
