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.
