ftp-proxy ktrace

ftp-proxy ktrace where kevent() doesn't return the new connection:

  313 ftp-proxy GIO   fd 2 wrote 33 bytes
       "listening on 127.0.0.1 port 8021
       "
   313 ftp-proxy RET   write 33/0x21
   313 ftp-proxy CALL 
kevent(0x5,0x800a3c000,0,0x800a3b000,0x40,0x7fffffffe780)
   313 ftp-proxy STRU  struct kevent[] = {  }
   313 ftp-proxy STRU  struct kevent[] = {  }
   313 ftp-proxy RET   kevent 0
   313 ftp-proxy CALL 
kevent(0x5,0x800a3c000,0,0x800a3b000,0x40,0x7fffffffe780)
   313 ftp-proxy STRU  struct kevent[] = {  }
   313 ftp-proxy STRU  struct kevent[] = {  }
   313 ftp-proxy RET   kevent 0
   313 ftp-proxy CALL 
kevent(0x5,0x800a3c000,0,0x800a3b000,0x40,0x7fffffffe780)
   313 ftp-proxy STRU  struct kevent[] = {  }
   313 ftp-proxy RET   kevent -1 errno 4 Interrupted system call
   313 ftp-proxy PSIG  SIGINT SIG_DFL code=SI_KERNEL

Between the "listening on" part and the SIGINT at the end a connection was
received by ftp-proxy, and kevent() didn't return it.
