<pre id="var-docstr">filler-func will be called in another thread with a single arg
'fill'. filler-func may call fill repeatedly with one arg each
time which will be pushed onto a queue, blocking if needed until
this is possible. fill-queue will return a lazy seq of the values
filler-func has pushed onto the queue, blocking if needed until each
next element becomes available. filler-func's return value is ignored.</pre>
