> It is currently very hard to debug memory issues, in particular memory leaks, in mesos.
> An alluring way to improve the situation would be to change the default malloc to jemalloc, which has built-in heap-tracking capabilities.
> However, some care needs to be taken when considering to change such a fundamental part of mesos:
>   * Would such a switch have any adverse impact on performance?
>   * Is it available and will it compile on all our target platforms?
>   * Is the jemalloc-licensing compatible with bundling as third-party library?
