Hi! 
 
The buffer in /python/dist/src/Modules/fcntlmodule.c 
ist hardcoded to 1024 byte. It would be cool if would be dynamic 
allocated or at least make it 10k big. 
 
my argnument has an size of 1816 byte 
 
        char buf[1024]; 
..... 
                       if (len > sizeof buf) { 
                               PyErr_SetString(PyExc_ValueError, 
                                       "ioctl string arg too long"); 
                               return NULL;

Python 2.3 already does something like this.

You have to pass in an array.array (or other writable buffer).
