Hello Monks!

I've recently discovered the IPC::Shareable module. It seems to really fit a need I have in one of my present projects. However, in using it, I'm finding that my code is crashing a lot whenever the hash that I am tying execedes the amount of space that I am allocating for it. :(

Questions:

  1. Is there any way to find out how much actual memory is being used by an un-tied hash? I'd like to be able to benchmark the object that I'm using to try to find out an appropriate size to specify when tying it. I know you can find out the number of keys and buckets, but that doesn't really help much in this case.
  2. Is there any way to find out what percentage of the allocated memory an IPC::Shareable object is using?
  3. Ideally, I'd like to be able to monitor how close I am to execeding the allocated memory bounds and then re-allocating a larger memory space when that happens. Is this possible?

Thanks in advance for any pointers!
