Detailed Description

Run-time heap statistics.

Note:

(double)searches/allocs gives mean number of searches per alloc while max_search gives maximum number of searches ever performed on a single call to alloc.

the statistics is always gathered. I believe the imposed overhead is rather small. Feel free to make it compile-time option if you think the overhead is too high for your application.
