fix: tummy stuck when calculating log size

Browse Source 
Timmy can get stuck on proc.join() if queue has not been collected
and the queue does not fit into the system pipe buffer.

This fix adds a loop in which we try to get data from the queue and
then join the process but with a 1 second timeout, so we don't block
forever.
