While for testing the current bitmask passed to `PIKA_MPI_COMPLETION_MODE` is convenient, the values are not very transparent to a user setting the values. It'd be nice to split up the...
We should set it to something that performs reasonably well, while providing a "safety" in terms of running continuations in new tasks etc.
Testing what effect this has on performance. The hope is to have less variance, but given that we don't pass/fail PRs based on these results, it may not be necessary...
Add a pool create option to 'init params' - this allows pika to call mpi pool_create at startup and remove the need for the user to setup a polling pool...
