Does this problem occur in =app-shells/bash-4.4*? Does this problem occur with FEATURES="-ipc-sandbox"? Does this problem occur with FEATURES="-network-sandbox"? Does this problem occur with FEATURES="-pid-sandbox"?

sys-apps/portage-2.3.57 contains some FEATURES="pid-sandbox"-related changes. Please check if this bug still occurs in this version.
It still hangs with portage-2.3.57.
When I run `ebuild bash-5.0.ebuild test`, I see the ebuild process receive some kin of stop signal like SIGSTOP or similar, just as though ^Z has been typed at the terminal. Then, if I use `fg` to send SIGCONT, the test phase completes successfully.
This issue is suppressed by calling os.setsid() in the pd-ns-init preexec_fn.

Confirmed: the process no longer hangs with portage-2.3.58.
