 The last line printed by parallel make is usually irrelevant, it can be stuck 
by another job that started before. So it's necessary to check processes 
launched by make (on Linux I'd do 'pstree -pal', I don't know if that works 
in cygwin).

 But first I'd check if this isn't the recent cygwin problem that was causing 
make getting stuck.
