Some quotes from Hyatt on this issue:

<dhyatt> it's not obvious how to change it without hurting perf
<dhyatt> the tentative idea i had was to refcount FontDatas
<dhyatt> and just pretend like FontPlatformData is always a "temporary"
<dhyatt> to avoid massive refcount churn on the fontplatformdata
<dhyatt> if you look at fontdata's destructor
<dhyatt> (i guess simplefontdata now)
<dhyatt> it does actually have code to delete the HFONT and release the
cgfontref
<dhyatt> it never gets called
<dhyatt> i just mean i wrote the code assuming that someday the fontdatas would
get destroyed
<dhyatt> purged from the cache etc
