RE: XFree leaking memory?

["Konstantin N. Kudin" <kostya at rice dot edu>]

 Harold,

 I did some tests and basically when I open an xterm the XWin size goes up
by about 30-50 Kb. When I close it, it stays the same (enlarged). When I
open a remote xterm and display it on my machine, same thing happens, i.e.
XWin size increases when xterm appears and stays at the same level when
xterm is closed.

 Another issue is that xclock manages to grow from about 5 Mb when fresh
to about 10 Mb in a week.

 Also, all the xfree components seem to require obscene amounts of memory,
7 Mb per each xterm, 5 Mb for xclock, 5 Mb for fvwm pager, etc. Is this
because the required libraries are statically linked with these
applications such that everything has to keep its own set of libraries?
The end result of this behaviour is that 512 Mb of RAM that I have become
insufficient in a few days and I have to restart Xwin to get things under
control.

 I hope this helps ...

 Konstantin
