I finally got it resolved

On AIX, there's not only ulimit, but there are additional memory
constraints 
for processes defined using the LDR_CNTRL environment variable.

Setting LDR_CNTRL=MAXDATA=0x80000000 means a Limit of 2GB for 32bit
processes, 
which was (in my case) enough.

The high memory requirement is probably a result of issue #3593 ,
http://subversion.tigris.org/issues/show_bug.cgi?id=3593 , and thus 
should disappear in 1.7.

As a workaround, I'll dump in chunks.
