Is mouth a machine?  What architecture.

I am actually seeing a strange 'Operation not permitted' problem on my
386 Debian box with the clone test at the moment.  This happens with
or without your patch.

Executing on host: gcc ./ltrace.minor/trace-clone.c  -g  -lm   -o ./ltrace.minor/trace-clone    (timeout = 300)
__libc_start_main(0x80483fe, 1, 0xbfc01ac4, 0x80484c0, 0x8048470 <unfinished ...>

)                          = 10582

Modulo the error that already exists, this works on my Debian x86 box.

I remember reading this message; maybe that has something to do with
it?
