Exactly! Even closing the window doesn't clean up everything:

IDL> .RESET_SESSION
IDL> help,/heap
Heap Variables:
# Pointer: 0
# Object : 0
IDL> p=plot(findgen(10))
IDL> help,/heap
Heap Variables:
# Pointer: 5031
# Object : 4425
IDL> obj_destroy,p ; Window is still there
IDL> help,/heap
Heap Variables:
# Pointer: 5031
# Object : 4424
...close window...
IDL> help,/heap
Heap Variables:
# Pointer: 1171
# Object : 1399

This would make sense if the next plot reuses some of these objects:

IDL> p=plot(findgen(10))
IDL> help,/heap
Heap Variables:
# Pointer: 5050
# Object : 4445

It seems to do that, but some objects are not reused/deleted, so
plotting+closing many times increases heap allocation. This serves no
purpose that I can think of.
