  18. I wrote this tool I call watchlib.  It setfunctions a whole library
  19. with an assembler stub (using the pragma file) which sends a message
  20. to the process.  This allows the return value and the register arguments
  21. to the function call, plus the name of the function to be printed.
  22. What I saw was that autopoint is (as you might imagine, but never guess) doing
  23.  
  24. LockIBase()
  25. WhichLayer()
  26. UnlockIBase()
  27.  
  28. continuously.  You will notice that it is above priority 0, so there
  29. is little wonder why things slow down...
  30.  
  31. e.g.
  32. AutoPoint: D0=0x0     =LockIBase(D0=0x0) intuition.library
  33. AutoPoint: D0=0x37b7c0=WhichLayer(A0=0x28cee8,D0=0x185,D1=0x4e) layers.library
  34. AutoPoint: D0=0x0     =UnlockIBase(A0=0x0) intuition.library
  35.  
  36. While that is going on, you of course also have input.device doing things
  37. like...
