Subject:	Re: Make hung in WaitForMultipleObjects inside Cygwin
References:	<20010228155722 DOT 21696 DOT qmail AT lizard DOT curl DOT com>

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.
