heap memory usage in L4 drops/oskit task

*sigh* The same program seems to work fine in linux, I've tried
running it through valgrind too without problems. Unlikely as it
seems, I'm starting to suspect errant behaviour in drops or oskit.
Perhaps the different thread scheduling exposes a bug in my program
somewhere, or perhaps the semaphores  are not working as expected (in
linux I get to use the pthread mutexes, no such luxury in drops/oskit)

Thanks for the help so far,
