net/tor on NetBSD 9 earmv7hf hangs

[John Klos <john%ziaspace.com@localhost>]

I've run net/tor on NetBSD 8 on earmv7hf, but on NetBSD 9, it hangs. 
Control-t says:

[ 102164.5391729] load: 0.03  cmd: tor 856 [parked] 0.01u 0.02s 0% 3432k

ktrace shows it gets here, then nothing:

  9106      1 tor      CALL  __sigaction_sigtramp(SIGIO,0x7ffa5f9c,0,0x7b2989c8,2)

Does anyone have any clues?
