# The problem that I have
"emerge" program fails due to the error, "qemu: qemu_thread_create: Invalid
argument".
"emerge" is Gentoo's package manager that compiles and installs packages.
# Workaround
Disable pid-sandbox in emerge.
# How to reproduce the issue
Execute
unshare --pid -- echo hello world
or
python -c "import portage.process; portage.process.spawn(['echo',
'hello', 'world'], unshare_pid=True)"
