# Different boxes we run on may have different amount of hw threads

# Originally we used to read /sys/devices/system/cpu/online
# but it is not available these days (odd). Thus we fall to
# the alwas-present /proc/cpuinfo
# The oneliner is a tad convoluted - basicaly what we do is
# slurp the entire file and get the index off the last
# `processor    : XX` line

# We also divide the result by a factor, otherwise the travis VM gets
# overloaded (the amount of available swap is just TOOOO damn small)
# Add one to make sure it doesn't go to zero
