That raises the question: Does it matter that uClinux is for
microcontrollers without a MMU, which the blackfin unsurprisingly lacks?
Does it matter that a poorly disciplined thread can crash not only other

All the data continuously generated in your IT infrastructure
contains a definitive record of customers, application performance,
security threats, fraudulent activity, and more. Splunk takes this
data and makes sense of it. IT sense. And common sense.
