// This test should include:
// -------------------------
// * Load a small drumkit and check that the memchecker doesn't warn.
// -> this assumes that the system is not already swapping which is sane imo.
// * Load a huge drumkit and check that the memchecker does warn.
// * Load a kit where we exactly know the size of the audio files and check if it's correct.
// * Check if the amount of free ram is in a realistic range.
//
// NOTE: This test will fail if your system is currently swapping or has an extremely small amount of RAM.
