Subject: t/80proxy.t fails on 96-core machine with parallel-harness

On a 96 core'd machine with HARNESS_OPTIONS="-j99", for some reason, 80proxy.t fails tests:

t/80proxy.t ..................... Dubious, test returned 255 (wstat 65280, 0xff00)
Failed 130/136 subtests

Forcing single job testing makes this problem go away, at the expense of greatly slowing down the execution of the test suite

Full test suite output and perl -V output attached in case any of it is useful.

Looks like the resource conflict is between t/80proxy.t and its variant, t/zvg_80proxy.t , due to being based on the same code.

You can reproduce this on a machine with only a handful of cores via:

prove -blr -j3 t/80proxy.t t/zvg_80proxy.t

Just it typically takes a lot more cores for this to happen accidentally.
