   * Fundamentally, there's not really anything we can do about that. In the unlikely event that it
   * comes up in practice (maybe through some kind of sanitizer-like testing that intentionally
   * inflicts spurious interrupts on us?), we might have to accept some flakiness or disable some
   * tests, at least under whichever environment (JRE or Android) we see such problems.

 * Null row keys, columns keys, and values are not supported.

 * <p>Lookups by row key are often faster than lookups by column key, because the data is stored in
 * a {@code Map<R, Map<C, V>>}. A method call like {@code column(columnKey).get(rowKey)} still runs
 * quickly, since the row key is provided. However, {@code column(columnKey).size()} takes longer,
 * since an iteration across all row keys occurs.
