For the last few weeks I've been experiencing the same, and the 
offenders always seem to be either bash (not ash) or make.  It is 
important to note that I track cygwin's CVS head, so I had chalked it up 
to the on-going signal work.  I've found that running deep `make`s or 
running the autotools in succession (such as in the case of triggering 
the AM_MAINTAINER_MODE routines) often triggers this problem for me on 
my Dual Athlon MP 2400+ Win2K box :-(.  I've been extremely busy working 
on other things, I just grumble, kill the deadlocked process and its 
children, then restart the parent.  Attempting to debug gdb/strace, as 
you've discovered, is quite fruitless.

Cheers,
Nicholas
