There are severals memory allocator on Solaris. You can choose what you need. See mapalloc (it uses mmap insted of srbk) mtmalloc (optimized fro multi threaded apps) mumem_alloc watchmalloc bsdmalloc maybe more. What I heart is that standard malloc is not good, but it is still here for compatibility reason with old application which depends on some functionality.
