cmake hang ... again

[Chavdar Ivanov <ci4ic4%gmail.com@localhost>]

Hi,

It may or may not be linked to the recent rather enthralling
discussion about the entropy; I don't know. I've asked for ideas in
the past, but couldn't figure out what to do if it hits me again.

Usually I run -current on amd64, updating the systems on average 2-3
times a week; I also use pkgsrc-head and again, 2-3 times a month I
cvs update my pkgsrc tree, together with a ' git pull' in wip, and I
run 'pkg_rolling-replace'.

Each and every run of pkg_rolling-replace gets me to a seemingly
identical hang in cmake in a single package - misc/kdepim4 , in
apparently the same spot. with similar trace. Attaching to the process
with gdb and quitting gets cmake to complete without any other action.
I've posted earlier the trace; here is another one, if it may be of
use:
