Problems with r40628

[Austin Hastings]

Howdy,

I spent today paying the svn update tax for parrot, going from 40290 to 
latest, then using svn-bisect to figure out what was breaking my stuff.
 
Presently, my Close compiler doesn't work. That's my fault. But it 
doesn't work in a particular way that gives me hope for light at the end 
of the tunnel.

When I updated, though, it started to not work in a different way. It 
would consume all the available memory (700m or so) and then I would get 
a "Killed" written out.
 
That struck me as suspicious - it seems more like a kernel type Killed 
than a shell type "Killed due to resource limit blah blah".
 
At any rate, svn-bisect tells me that the problem comes from r40628, 
which naturally has a whole bunch of files associated with it. (It's 
never the one-line change that gets me... :( )
 
With no evidence whatsoever, I suspect that hte problem might lay with 
resizable pmc arrays, because I create a *bunch* of them in my debugging 
code -- pretty much M per function call, where 1 <= M <= 5.

Like the yellow-bellied coward that I am, I'm going to update to 627, 
and hope that some of the work I've seen going on today will fix this. 
If not, I'll put some more time into it when I get my Close refactor done.
