According to Popper, Samuel (US SSA) on 3/31/2008 2:48 PM:

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

|
| I am still having this problem (as evidenced by previous messages).
| I've come up with a bash script "test case" that demonstrates the
| problem:
|
| $ NUM=1; while true ; do echo $NUM; NUM=$(( $NUM + 1 )); done
|
| will run indefinitely,

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
