on the discarded side of brk() during cleanup. qemu was more aggressive
than the Linux kernel implementation of brk().

John Reiser adb0ca8250 Many changes for ELF shared libraries on Linux and Android 
Handling more than 2 PT_LOAD (and thus more than 1 executable PT_LOAD)
required extensive changes.  But the bonus is the infrastructure
to support a different (de-)compression algorithm for each PT_LOAD.
