That may not be totally accurate: a printf() after this while loop is never
executed. So there are two possibilities: either a single call to tsleep()
never returns, or the while loop never terminates.

I suspect that clock interrupts are an essential part of tsleep's timeout
mechanism, so perhaps I'm right that it's the former (single call to tsleep()
never returns).

But either way, the cause would be no clock interrupts are being delivered...
