+// 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.
