//
// 1. Launching one JVM per suite adds significant overhead for short-running suites. In

// metastores can be very slow so creating a fresh warehouse per suite is inefficient.
//
// 2. When parallelizing within a project we need to give each forked JVM a different tmpdir
// so that the metastore warehouses do not collide. Unfortunately, it seems that there are
// some tests which have an overly tight dependency on the default tmpdir, so those fragile
// tests need to continue re-running in the default configuration (or need to be rewritten).
// Fixing that problem would be a huge amount of work for limited payoff in most cases
// because most test suites are short-running.
