Not a good idea. The patch will get lost/forgotten when you hand the
completed code over the industrilisation team of intergration.

Sounds reasonable. Anyone with a non-trivial static initialiser
probably has enough MB of memory that 8K is will not be missed.

Change your static to dynamic initialisationm so it can be done in the
context of a thread you can control the size of the stack.
