In that case, +0 for at least reporting how much memory was being requested for the call that failed, even if that only turns out to be useful in our own test suite. -0 for the "currently allocated" suggestion though, as I don't see how we can provide a meaningful value for that (too much memory usage can be outside of the controller of the Python memory allocator, and we don't even track our own usage all that closely in non-debug builds).

Windows makes it easy to retrive the current process' memory statistics: http://hg.python.org/benchmarks/file/43f8a0f5edd3/perf.py#l240

As usual, though, POSIX platforms are stupidly painful to work with: http://hg.python.org/benchmarks/file/43f8a0f5edd3/perf.py#l202
