Sounds like the classic symptoms of http://cygwin.com/acronyms/#BLODA

| I am still having this problem (as evidenced by previous messages).

|
| $ NUM=1; while true ; do echo $NUM; NUM=$(( $NUM + 1 )); done
|

because it doesn't fork
|
| $ NUM=1; while true ; do echo `echo $NUM` ; NUM=$(( $NUM + 1 )); done
|
| Hangs pretty quickly,
because it forks a huge number of processes, and each fork is likely to be
tripped up by a BLODA
