Andreas said this:
"Unchecked allocation. Furthermore, the *dst = *src makes cleanup on
 error here a PITA. Would making pl_data reference-counted (via
 RefStruct) work instead?"

I hoped someone would implement the RefStruct stuff. I didnt anticipate
noone would even reply multiple pings

It would be needed to make sure teh issue Andreas raised is dealt with
either with or without RefStruct.

when I asked in that thread if others wanted to work on this i wouldnt
at the same time start working on it (that would be duplicate work
potentially) and then i of course forgot as noone even said "No"

that would be very good, yes

The day soldiers stop bringing you their problems is the day you have stopped 
leading them. They have either lost confidence that you can help or concluded 
you do not care. Either case is a failure of leadership. - Colin Powell
