[Bioc-devel] Package failed build on Windows - couldn't load related ExperimentHub dataset

Downloading the data to the local ExperimentHub cache seems quite 
unreliable. Not sure why. What doesn't help is that a temporary cache is 
used so the data needs to be re-downloaded each time. See my suggestion 
in the review process on GitHub for how to maybe work around this.
Well, the Windows machine tokay2 is a little bit old and not very fast. 
What doesn't help is that it has to run everything (examples and tests) 
twice, once in 32-bit mode and once in 64-bit mode. So yeah, the timeout 
is not too surprising here. When I manually ran 'R CMD check' on tokay2 
yesterday I noticed that the unit tests where taking a long time. So you 
would need to manage to make the whole thing run a little bit faster.

But first I would try to use a persistent ExperimentHub cache. This 
should improve speed on all the platforms. Let's discuss this on GitHub.

Thanks,
