I've checked with lanes HEAD, and it works as expected, all threads
are run concurrently. You seem to be running a lanes-2.x version. I am
pretty sure it should behave the same though. Here is what I get:

local lanes = require "lanes".configure(1)
print( os.date())
lanes.gen("os,base", function() os.execute('sleep 10 && echo
finished_sleeping') print( os.date()) end)()
lanes.gen("os,base", function() os.execute('sleep 10 && echo
finished_sleeping') print( os.date()) end)()
lanes.gen("os,base", function() os.execute('sleep 10 && echo
finished_sleeping') print( os.date()) end)()
lanes.gen("os,base", function() os.execute('sleep 10 && echo
finished_sleeping') print( os.date()) end)()
