 Example ktrace for this issue:
 
  24228      1 gdb      CALL  execve(0xbfffee18,0xbb8b6070,0xbb89fd00)
  24228      1 gdb      NAMI  "/usr/pkg/bin/tcsh"
  24228      1 gdb      NAMI  "/usr/libexec/ld.elf_so"
  24228      1 tcsh     EMUL  "netbsd"
   7933      1 gdb      RET   __vfork14 24228/0x5ea4
   7933      1 gdb      CALL  __wait450(0x5ea4,0xbfffe18c,0,0)
   7933      1 gdb      RET   __wait450 24228/0x5ea4
   7933      1 gdb      CALL  ptrace(PT_GET_PROCESS_STATE,0x5ea4,0xbfffe190,8)
   7933      1 gdb      RET   ptrace -1 errno 22 Invalid argument
 
 24228 == 0x5ea4
 and sizeof struct ptrace_state should be == 8.
 
 So I guess sys_ptrace_common.c:701 strikes and I really don't get how this
 is supposed to work.
