🚀 go-pugleaf

While I was thumbing through my TMON manual the other day,
I read through the section on the heap.  There is on option
in TMON to continually purge purgable-blocks from the heap.

The manual stated the most Macintosh application DO NOT pass
this test, because they still expect things they loaded into 
memory to be there.

My question is, is it necessary to call HNoPurge (for example)
every time you call GetResource, or can you expect things
loaded into the heap (like with GetResource) to at least be
there until the next ROM call?

Would a call like this be prone to this error:

    DrawPicture(GetPicture(1000), &r);
