I tried your *termcmd[] patch and it didn't fix the problem for me.
Just for the record I'm using an up-to-date archlinux distro with a
single-core 64-bit atom processor and a 3.10 kernel, current dwm-git
and st-git. The other case I know of is also archlinux, on an Inspiron
core-i5 processor, dwm 6.0 and st-git.

I'm glad you were the first to answer, Kudos. wayland needs more suckless. Keep on it and ignore the negative commentary. :-) I'm not sure how the suckless community feels about Wayland, but it seems like the core protocol is fairly lightweight, depends only on libffi, and is refreshing to work with compared to X. you'll get varied reactions on the list. I for one am happy to see the mingling between wayland and suckless stuff, since it potentially exposes the suckless philosophy, whatever it may be. Weston's goals are perhaps more orthogonal to suckless, but I think there is potential for a suckless compositor. I don't really expect there to be a suckless Wayland environment for a while, and maybe something better will come around before there is, but I think my rendering library could be useful in either case (the Wayland part is just buffer creation/management and is separate from the rendering part). -- Michael Forney mfor...@mforney.org Thanks --Carlos

I included some changes suggested by Markus in a rewrite of the netusage
functions for dwmstatus (attached; including an adapted dwmstatus-Makefile
for convenience).
Comments and criticism is welcome.
I will try to push a change request to the suckless sites git repo if
nobody threats to neuter my hamster over the code I wrote...
