[SciPy-dev] Does it worth the trouble to support non contiguous array in C extensions ?

I am about to push in SVN the first version of a small package to
compute lpc coefficients and lpc residual. I spent most of the time
trying to understand how to handle non contiguous arrays in various
parts of the C code...
Now, I am wondering: does it really worth the trouble ? I noticed
that most of the time, it is even faster (and obviously much easier to
code/debug/test, and much more reliable) to just copy the data in a
contiguous new array before processing with a C function expecting
Is there a general policy regarding thoses issues for scipy ? Is it
enough to write simple C extensions expecting contiguous arrays, and
converting input to contiguous layout if necessary ?
