Description

We have numerous test skips for 32bit windows + multithreading. Should we add something to onLoad that detects this and proactively sets arrow to single-threaded (using set_cpu_count() and / or options(arrow.use_threads)?).

Should we display a message that we did this and if someone wants to live experimentally they can increase that again?
