I would argue the exact opposite. We're talking ARM here, i.e.
embedded systems. On those systems, it's much easier to counter
performance issues than stability issues. If a box crashes, there's
nothing we can do - the customer will just return it.
I'm advocating the use of uClibc in the embedded boxes I'm writing
software for. My arguments are low resource consumption, and stability.
What am I going to tell my management if you purposefully remove the
stability? I will have to switch libcs. Again.
Make it work, then make it work fast.
