Hm, that's odd.  Python is supposed to ignore the locale when you use
atof(); the locale module exports a version of atof() that honors the
locale after you call locale.setlocale(locale.LC_ALL, "").

What platform are you on?  It seems that perhaps the Tcl version you
are using calls setlocale() on that platform?

I cannot reproduce this (on Solaris 2.7).
