Just a note that [thread|threading].stack_size() returns 0 to indicate
the platform default, and that value will always be returned unless an
explicit value has previously been set.
The Posix thread platforms (those that support programmatic setting of
this parameter) have the best support for sanity checking the requested
size - the value gets checked when actually set, rather than when the
thread creation is attempted.
The platform default thread stack sizes I can recall are:
Windows: 1MB (though this may be affected by linker options)
Linux: 1MB or 8MB depending on threading library and/or distro
FreeBSD: 64kB
