Bug#1142815: libipc-shareable-perl: autopkgtest uses insane amount of memory on loong64

Hi,

I was looking into why one of the loong64 host of ci.d.n was showing a 
spike is swap (we have 1.8 TB, it was used all) and loss of 
debci-workers and the culprit seems to be src:libipc-shareable-perl. I ran
"""
/usr/bin/autopkgtest --no-built-binaries  --timeout=30600 
--needs-internet=skip --timeout-install=9999 --user debci --apt-upgrade 
libipc-shareable-perl -- lxc --sudo --name elbrus 
autopkgtest-unstable-loong64
"""
manually on the host and killed it once top reported 70% memory use by 
perl (of the 127 GB). Swap plummeted from 74 GB to 10 GB.

I guess this means there's a memory leak somewhere on loong64. 
Otherwise, can you please limit the test to a reasonable memory footprint?

Paul
