Since 2.1, jemalloc does support using mremap to do large realloc()'s, although it seems to be off by default. You need "./configure --enable-mremap" to get it.
That's good news about sized deallocation, I hadn't noticed that there is an updated "N3778" proposal which apparently was accepted. I still haven't seen the dlmalloc work to support that show up in the main svn branch.
