Large embedded systems also like malloc-less solutions. In such systems you essentially have explicit use for all the memory you have and you don&#x27;t like to buy extra memory that is unused (reduces your margins). When you need to account for all memory needs and you use allocation schemes you need to create memory pools that are not too large (create waste) and not too small (performance bottle or deadlock source).<p>One such example are large SAN storage systems. We can have gigabytes or even a terrabyte of ram and still have very little spares (little by our standards &lt; 100MB for diagnostics and general OS nuisance).
