[perl #129228] [SEGV] concurrent network access segfaults in libmoar.so

[Zoffix Znet via RT]

I'm unable to reproduce this on HEAD Rakudo even with $n set to 40 and 
RAKUDO_MAX_THREADS set to 50.

What is your perl6 version (perl6 -v). Are you able to try this against HEAD 
[^1]? Yesterday a fix went in addressing issues in sockets and threads; and 
recently there have been many other async fixes.


[1] Steps to build:
    cd $(mktemp -d) &&
    git clone https://github.com/rakudo/rakudo/ . &&
    perl Configure.pl --gen-moar --gen-nqp --backends=moar &&
    make &&
    make install;
    ./perl6-m your-script.p6
