I had a quick look to the source of brainparty and didn't guess why this problem is happening. If it is indeed writing gigs of log files it would cause similar symptoms.

Btw, call SDL_GLES_Quit() (~ equivalent to eglTerminate()) before SDL_Quit(). The N8x0 leaks _a lot_ without such a call, but the N900 EGL driver seems to be more robust in this regard (so this won't improve the N900 situation).
