Since upgrading from F35 -> F36 and 2.34.x -> 2.36.0, I've seen Geary's web process crash several times when the netwokr process takes more than one second to start. I've also seen this twice today in Epiphany after upgrading Tech Preview from GTK 3 -> GTK 4. I'm not the only one. The backtrace looks like this:

(gdb) bt

Sadly, it looks like there are no recent changes to WebProcess::ensureNetworkProcessConnection, so I'm not sure what changed. Maybe we somehow made the network process slower?
