Sleeping doesn't work

[andreivasiliu]

Commands that attempt to sleep the current thread don't work, and will hang the whole thing:

sleep 1
top -d 1
timeout 1 ls

I think even this one, although I'm not sure if sleeping is what hangs it:

ping 127.1

It breaks the debugger too, e.g. help in Ctrl+A shows the debugger commands, but pc no longer does anything.

Querying the time however (e.g. with date) works fine, and time seems to advance quite nicely.
