mallinfo is the way to monitor how much memory an application is using.
Having to go through XML for that sounds like serious overkill. That
said, there are probably other pieces of information from malloc that
it actually makes sense to provide in xml form.

Actually you can read the memory usage for a process from /proc (e.g. /proc/PID/statm for a machine readable form). The information given by mallinfo is more detailed stuff about what the memory allocator is actually doing internally, not how much memory your process is using.

Both are needed. Mallinfo tells whether the process is fragmenting its
heap. Checking that may be a performance issue, so needing to parse XML
sounds strange. And if Glibc does allocs for the XML output, it would be
even stranger...

Indeed, it seems to me that a sysctl-like API would make more sense.
