There is no need for an additional API entry point: CreateThread already
has an argument to specify the stack size for the thread, so io-layer
just needs to be fixed to obey that argument and the entry point could
be added to metadata/.

As for the original issue: it makes sense to double the default stack
size for 64 bit apps, but I'm not sure increasing the stack size for mint is
a correct solution: if it requires 30+MB of stack, there is something 
else to fix. I would support using an environment variable to set the
stack size to non-default values, so that specific apps that may have
particular demands can be tweaked, both increasing the stack size (mint
until it's fixed) and decreasing it (think an app server with thousand
of threads on a 32bit system).
