This still hangs on MoarVM, but works on JVM (I didn't check the behaviour on 
JVM last year):

$ ./perl6-j -e 'my $proc = run($*EXECUTABLE, "-e", q| $*ERR.print("8" x 
8193);|,:out,:err); say $proc.out.slurp-rest; say "alive"'

alive
$ ./perl6-j --version
This is Rakudo version 2018.02.1-124-g8d954027f built on JVM
implementing Perl 6.c.
