   chEvtWaitTimeout() code if it is enabled.
 - Size optimization in the semaphores code, now the chSemWaitTimeout() just
   invokes the chSemWaitTimeoutS() inside its system mutex zone.
+- Added a threads create/exit/wait benchmark to the test suite, the system
+  is capable of 81712 threads started/terminated per second on the reference
+  LPC2148 board. The figure is inclusive of two context switch operations
+  for each thread.
 - Minor improvement in the LPC214x serial driver, unneeded events were
   generated in some rare cases.
 - Fixed a chSysInit() documentation error.
