Storagenode.exe stopping for too long, for 10h+

Right now I can see the only one workaround for almost any problems with filewalkers, include the not killing child processes, is to disable the lazy filewalker with the parameter:

@Alexey

# run garbage collection and used-space calculation filewalkers
# as a separate subprocess with lower IO priority (default true)
pieces.enable-lazy-filewalker: false
