memory usage

[Stephen Berman]

With GNU Emacs 22.1.50.3 (i686-pc-linux-gnu, GTK+ Version 2.10.6) of
2007-06-03 on escher I have the impression, though I cannot be
certain, that memory usage is greater than it had been with earlier
builds.  My current session has been running for 13+ hours; top shows:

  PID %MEM  VIRT SWAP  RES CODE DATA  SHR nFLT nDRT S  PR  NI %CPU COMMAND
 4707 54.5  623m 349m 274m 1476 602m 8336 8928    0 S  17   0  0.0 emacs
 4015 10.5  145m  92m  52m 1516 114m 2596 1813    0 S  15   0  0.7 Xorg
 6545  7.3  174m 137m  36m 9520 137m 9.9m 1047    0 S  15   0  0.0 firefox-bin

and increasing steadily; about half an hour ago it was like this:

 4707 44.9  551m 324m 226m 1476 529m 8576 5149    0 S  18   0  0.0 emacs
 4015 10.7  141m  87m  53m 1516 110m 3260 1322    0 R  15   0  0.7 Xorg
 6545  7.8  174m 134m  39m 9520 137m  11m  951    0 S  15   0  0.0 firefox-bin

I currently have 28 buffers with a total size 4134853, 14 files, no processes.

M-: (memory-use-counts)
    => (19357612 63265 4733430 80473 141277128 1753754 446815 4002874)

M-: (memory-limit)
    => 754048

These are also increasing steadily (memory-full is still nil).

Are these numbers within normal bounds or cause for concern?
