For streaming files, you want something pausable; there are existing
producers which don't use threads, and there will presumably be a tubes
equivalent. Maybe having the tubes one use threads by default is a good
For getting a file as a string, you can just do:
d = deferToThread(lambda path: FilePath(path).getContent())
For more complex usage patterns, you'll probably want to write custom code
using deferToThread/deferToThreadPool anyway.
