Comment(by steve@…):

 == Build of 'boost' stalled for 4.5 hours with massive CPU load ==

 This was also on a new i7 iMac running 10.6.2 (is this an i7 issue?).

 My weekly 'port-selfupdate+upgrade' script ran as root from launchd at
 03:00 this morning.

 It uses 'port -v -p -u upgrade outdated' to update the ports.

 Found it stalled at 07:30 this morning.

 There were 8x 'g++' builds (one for each core?) under the 'bjam' process,
 each running 'cc1plus', each of which was using 83% of its own CPU!

 No further output since 03:05 (according to the log time stamp, and
 assuming that there wasn't much unbuffered output).

 Took samples of the 'bjam', 'g++' and 'cc1plus' processes.

 Found this ticket with the same problem.

 Killed build with 'sudo killall cc1plus' to get things back to normal.

 Summary of stdout from the script (nothing bar the download in stderr):

 Complete output from 'boost' build is in the attached file, together with
 a screenshot of Activity Monitor, and samples of the processes (in case
 that's relevant or helpful).

 Hope this helps!
