 One more thing:
 
   |      11172      1 sh       CALL mmap(0,0x1000,PROT_READ|PROT_WRITE,0x1002<PRIVATE,ANONYMOUS,ALIGN=NONE>,0xffffffff,0,0)
   |      11172      1 sh       RET   mmap 126131311058944/0x72b73bfda000
 
 That's very odd, sh doesn't call mmap() anywhere (and doesn't use stdio
 for input/output either) and doesn't dynamically load anything either
 (libc and libedit should have been loaded at startup).   Are you sure
 that's the NetBSD /bin/sh doing that?
 
 In that sh, do "echo $NETBSD_SHELL" and show what it says please.
