make -j hangs? anyone else?

[Chris Abbey <cabbey at bresnanlink dot net>]

Is anyone else seeing random, intermittent hangs with multi-process
makes? basically what's going on is that it gets through with a set
of compiles and then just sits there. Everything it has claimed to
have started has finished, there are no compiler processes left, just
make and it's sh twiddling their thumbs....

~ $ ps
       PID    PPID    PGID    STIME COMMAND
       174       1     174 20:59:51 /usr/bin/bash
       195     174     195 21:52:03 /usr/bin/make
       230     195     195 21:52:03 /usr/bin/sh
       124     230     195 21:52:04 /usr/bin/make
(I've trimmed this to the relevant processes)

killing 124 does no good. it takes a kill 230 to break the make
process loose and exit, at this point the child make process is
orphaned (ppid=1) and it takes a kill -9 to get rid of it. It
doesn't seem to be reliable when it will hang, just that I can't
get through a complete jikes build without hitting this once or
twice.

I'm on a dual P2 450mhz, loads of memory and compiling from a
fast ntfs stripe set, there is no other (appreciable) load on the
system (when it hangs the total CPU consumption is 0% most of the
time, occasionally blipping up to 1% for a single refresh of
task manager.)

here's the version info for relevant packages, and a cygcheck,
basically it's "current" as of earlier today.
