Kernel updates:

+ Added vTimerSetTimerID() to compliment vTimerGetTimerID().  Now the timer ID can be used as timer local storage.
+ Updated comments and added some additional assert() calls.

Win32 port:
+ Some changes to allow easier 64-bit builds

PIC24/dsPIC port:
+ Added NOP after disable interrupt instruction.
