Including blib in $PERL6LIB for this particular module, causes it to freak out and nom memory

Strange test problem for perl6-facter

env PERL6LIB=/Users/adrian/Development/Perl6/perl6-facter/blib/lib:/Users/adrian/Development/Perl6/perl6-facter/lib: prove -v -e 'perl6' -r t/resolution-exec.t

Fails

env PERL6LIB=/Users/adrian/Development/Perl6/perl6-facter/lib:/Users/adrian/Development/Perl6/perl6-facter/blib/lib: prove -v -e 'perl6' -r t/resolution-exec.t

Works

# why would including the blib directory in $PERL6LIB cause perl6 process to consume huge amounts of RAM (until it is manually killed?)

Further to this,

Removing the compiled PIR version of Facter::Util::Resolution allows the test harness to "work" and continue.

But rebuilding it with:

env PERL6LIB=/Users/adrian/Development/Perl6/perl6-facter/blib/lib:/Users/adrian/Development/Perl6/perl6-facter/lib:/Users/adrian/Development/Perl6/ufo/lib:/Users/adrian/lib: perl6 --target=pir --output=blib/lib/Facter/Util/Resolution.pir lib/Facter/Util/Resolution.pm

Causes the error again
