yes .text size is important for the embedded people but performance 
also. so if perf is not impacted and .text increase is reasonable, 
it's interesting to remove the config option and clarify the code
at the same time. This was the case of uts and ipc ns.  

user ns is far from complete and should be kept experimental.
