Apparently, duplicating this problem under smake was easier than we
thought it would be :-). Shortly after we started running builds
under smake to try to catch this hang, it appears to have recurred.
The Make PID that is hung is 1118. I don't want to include it here
since it's almost 4Mb uncompressed, but it's available for download,
gzipped, at <http://www.mit.edu/~jik/smake.1118.txt.gz>. The last 50
lines of the smake output are included below.
Any suggestions for how to debug this further would be much
appreciated.
