Hi,

NetBSD current is broken with something signal related problem?

% tail -F /var/log/messages
^Z
[3]  + 3335 suspended  tail -F /var/log/messages
% fg
tail: kevent
% 

I'm using NetBSD current (2011/09/03 00:32) and I ktraced:

  4155      1 tail     CALL  read(3,0x7f7ff7701000,0x4000)
  4155      1 tail     GIO   fd 3 read 0 bytes
       ""
  4155      1 tail     RET   read 0
  4155      1 tail     CALL  __kevent50(4,0x7f7fffffd950,2,0,0,0)
  4155      1 tail     RET   __kevent50 0
  4155      1 tail     CALL  read(3,0x7f7ff7701000,0x4000)
  4155      1 tail     GIO   fd 3 read 0 bytes
       ""
  4155      1 tail     RET   read 0
  4155      1 tail     CALL  __kevent50(4,0,0,0x7f7fffffd950,1,0)
  4155      1 tail     RET   __kevent50 -1 errno 4 Interrupted system call
  4155      1 tail     CALL  write(2,0x402ea6,6)
  4155      1 tail     GIO   fd 2 wrote 6 bytes
       "tail: "
  4155      1 tail     RET   write 6
  4155      1 tail     CALL  write(2,0x7f7fffffcf60,6)
  4155      1 tail     GIO   fd 2 wrote 6 bytes
       "kevent"
  4155      1 tail     RET   write 6
  4155      1 tail     CALL  write(2,0x603be7,1)
  4155      1 tail     GIO   fd 2 wrote 1 bytes
       "\n"
  4155      1 tail     RET   write 1

Best regards.
