In autobuilder testing we regularly see glib-networking ptest fail with:

GLib-Net:ERROR:/usr/src/debug/glib-networking/2.74.0-r0/tls/tests/connection.c:1944:simul_read_thread: assertion failed (error == NULL): Resource temporarily unavailable (g-io-error-quark, 27)
Bail out! GLib-Net:ERROR:/usr/src/debug/glib-networking/2.74.0-r0/tls/tests/connection.c:1944:simul_read_thread: assertion failed (error == NULL): Resource temporarily unavailable (g-io-error-quark, 27)
FAIL: glib-networking/connection-openssl.test (Child process killed by signal 6)
SUMMARY: total=4; passed=3; skipped=0; failed=1; user=0.9s; system=0.4s; maxrss=10708
FAIL: glib-networking/connection-openssl.test (Child process killed by signal 6)

The test should probably retry in this situation so test a patch which does this.

Upstream-Status: Pending [testing to see if patch resolves the issue]
