[Bug libc/208] New: mallinfo returns incomplete information

[carlton at bactrian dot org]

Judging from both the implementation and an experiment, mallinfo()
only returns information about the memory used in the current arena.
This doesn't seem to be mentioned anywhere in the info file or
in malloc.h, and I don't see how it's useful information, given that
arenas don't seem to be exposed in the user interface.

I am aware of malloc_stats(), but I don't always want the statistics
dumped to stderr.  (Incidentally, malloc_stats() doesn't seem to be
mentioned in the info pages.)

The mallinfo() API was discussed on libc-alpha recently, and the
conclusion was that the info provided do not really match the
current implementation.  It apparently was part of SysV, but has
been dropped from later version of the unix standard.  It should
probably be removed and replaced with a better API.  The current API
do not handle large amount of memory and isn't working very well
in 64bit environments.

mallinfo won't be extended.  We will have a new interface at some point.
