Latest findings: * The deepest loop that actually never exits is actually the `while not os.path.exists(fexit):` in the `eofcat` script. This is because the `block = os.read(0, 1000000)` always reads nothing. * From the guest: * `head`ing the `stdin` file doesn't help. * `tail`ing the `stdin` file does help, it unblocks the loop, just the same way as `stat`ing it. * From the host: * `stat`ing `stdin` doesn't change anything. * Appending more data to it doesn't change anything either. * This adds up with the fact that it's a kernel change in the guest that triggered the bug. * That `stdin` file is stored on a 9p shared FS. This might be a related change, but nothing confirmed yet: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c9b93cafb69cbbbe375de29c1ebf410dbc33ebfc
