Process forking does not work with XDebug

[tgr]

PsySH just hangs forever at the stream_select call in ProcessForker.

Psy Shell v0.11.8 (PHP 7.2.31-1+0~20200514.41+debian9~1.gbpe2a56b+wmf1 — cli) by Justin Hileman

with Xdebug v2.7.2, Copyright (c) 2002-2019, by Derick Rethans

I think this used to work in the past and I'm not sure what on my system changed, so it might be specific to the PHP, XDebug or PsySH version.
