The logging library doesn't seem to like it when multiple logging actions are
interleaved with each other, as can happen if we use unsafeInterleaveIO.
This leads to a deadlock.
To work around this, introduce a CachedIO type so that we can explicitly
control ordering of effects and avoid such situations where logging is
interleaved.
