reproduce this issue:
version:
mingw-qemu-ga-win-101.2.0-1.el7ev
Steps:
1. bootup win2016 guest and run qemu-ga.
2. run powershell.exe and execute command "PS C:\Users\Administrator> while(1) { Get-Process -ProcessName qemu-ga; sleep 5 }" while running command "cat <(for i in {1..1000}; do echo '{"execute":"guest-get-osinfo"}'; sleep 2; echo '{"execute":"guest-get-devices"}'; sleep 2; done) | nc -U /tmp/qga.sock > log" on host.
actual result:
handles raise up without limit, actually it should be limited to less than 300, but now it cause resource leak.
Expected result:
handles maintain a stable value.
