+Allocate large numbers of huge BigIntegers in rapid succession. Most of the

+the garbage collector often enough to prevent us from running out of memory.
+
+The test allocates roughly 10GB of native memory, approximately 1MB of which
+will be live at any point. Basically all native memory deallocation is
+triggered by Java garbage collection.
+
+This test is a lot nastier than it looks. In particular, failure on target tends
+to exhaust device memory, and kill off all processes on the device, including the
+adb daemon :-( .

+Regression test for bug related to interaction between instrumentation
+installation and class redefinition.
+
+Redefining a class does not update the instrumentation stack of a thread.
+This is generally fine because the method pointer in the instrumentation
+stack is only used for some sanity-checks, logging and method-exit events
+(where it being the non-obsolete version is advantageous). Unfortunately some
+of the checks fail to account for obsolete methods and can fail sanity
+checks.
