In my case I see it with Windows Task Manager, the PF Usage displays. Memory
usage slowly increases over time, seemingly when there is lots of process
creation going on such as during large makes. On my systems with paging turned
off, eventually all memory is consumed and things really go to hell.
I've found an easy testcase. Remember this bash script?
while [[ ! -z $mypath ]]
if [[ -z $mypath ]]
echo "Test failed.. Path is empty."
I run this for a while and see gradually increasing memory usage. Even when
all Cygwin processes are subsequently exited, that memory is not released. I
also recoded that script for ash and ksh and the same thing happens, so it's
not bash's problem.
