I was seeing some unusual delays under 4.99.55 but at the same time I 
didn't bother checking as I was seeing the _lwp_ctl problem. That box 
has since been updated. On another box I have:

NetBSD gogeta.internal 4.99.55 NetBSD 4.99.55 (XEN3_DOM0) #0: Tue Mar 11 
19:59:08 EST 2008  
root%spike.internal@localhost:/usr/obj/sys/arch/i386/compile/XEN3_DOM0 i386

# time sleep 3 ; time sleep 5 ; time sleep 10
   3.01s real     0.00s user     0.00s system
   5.01s real     0.00s user     0.01s system
  10.01s real     0.01s user     0.00s system

So I was either imagining it or I updated independently amd they were 
out of sync, which is highly likely.

An up-to-date domu shows:

NetBSD sammy.internal 4.99.58 NetBSD 4.99.58 (XEN3_DOMU) #0: Wed Mar 26 
16:49:41 EST 2008  
root%spike.internal@localhost:/usr/obj/sys/arch/i386/compile/XEN3_DOMU i386

$ time sleep 3 ; time sleep 5 ; time sleep 10
   3.01s real     0.00s user     0.00s system
   5.01s real     0.00s user     0.01s system
  10.01s real     0.01s user     0.00s system
