Hmm, I don't think we should encourage using these APIs. It just makes 
the code less clear and people will waste time wondering what they're 
for. It's just legacy cruft from a bygone age and there's not a huge 
amount of point unless people are desperate to use the +olemalloc 
channel (I suspect not).
