       Show HN: Heap Explorer
        
       I wrote a little LD_PRELOAD library that makes it easy to inspect
       and interact with a running program's glibc heap.  It's fun to
       pause processes, free a bunch of their allocations, then resume
       them. Most of the time, the processes continue as though nothing
       happened, but sometimes they do interesting things :)
