+ * ASSERTION:

+ * SECTION: Buffers and Buffering/Buffer Resizing Policy;
+ *	Options and Tunables/specsize;
+ *	Options and Tunables/bufresize
+ *
+ * NOTES:
+ *	On some small memory machines, this test may consume so much memory
+ *	that it induces memory allocation failure in the dtrace library.  This
+ *	will manifest itself as an error like one of the following:
+ *
+ *	    dtrace: processing aborted: Memory allocation failure
+ *	    dtrace: could not enable tracing: Memory allocation failure
+ *
+ *	These actually indicate that the test performed as expected; failures
+ *	of the above nature should therefore be ignored.
