FWIW, it works on QubesOS, which is Xen based. Though it works only in my Fedora and Debian VMs, but not on my Archlinux-based one.

I think that's because I have WINE installed in the Archlinux VMs, since that's what gets started when I run ./redbean.com. But even after I remove WINE, it still doesn't work, I probably have to restart (i.e. remove WINE from the TemplateVM, not the AppVM) for it to work.

In any case, incredible work, I am in awe!
