The number of threads is limited by available RAM only. Use
NutHeapAvailable() to check this.

NutThreadKill will remove all memory occupied by the kernel when
creating a thread. In fact this is done by the idle thread.

Any heap memory allocated by your application must be released by the
application. This includes closing open files etc.

To check this, you may enable NUTDEBUG_HEAP in the Configurator and
rebuild Nut/OS. Within your application you can call NutHeapDump(stdout)
to get a dump of all used heap fragments, including the information,
where they had been allocated.

(No need to modify UserConf.mk anymore, it's configurable in Configurator.)
