dear Cygwin developers:
i have a bash script which apparently causes an
exhaustion of system resources.
which "resources" i am unclear about - it does not
seem to be memory.
the consequences of running it, at a minimum, are that
1) the script fails at some point,
2) no further Cygwin executables will run,
3) dialout to an internet service provider fails,
4) a number of non-Cygwin executables do not operate
properly.
below is a simple script which will make the problem
happen and a partial transcript of a Cygwin console
session where it is invoked.
do you have any ideas on this issue?
