OK.  But it is generally considered a bug in confdefs.h if you
configured a system correctly and get an error like this.  But
running out of stack space before task control blocks may or may
not indicate a bug.

Yes.  If you configure some higher level abstract service, it will
try to reserve enough resources for itself.  File descriptors, Ada
tasks and a few other items implicitly add other resources.  But for
the most part it is just extra semaphores.
