02_code.t hangs on Windows about proc-guard HOT 3 OPEN

If 02_code.t hangs on Windows under Strawberry Perl version 5.14.4 or higher,
this patch might be helpful.

I tested Strawberry Perl:
v5.14.4
v5.18.4
v5.20.3
v5.22.2
v5.24.0
on Windows 7(32bit).
)

Hope this help.

Thank you,

from proc-guard.

It still hangs with Strawberry 5.26 64 bit/Windows Server 2016

from proc-guard.

I did some investigation, and it seems we need to replace the kill code with kill_gently() from IPC::Cmd:

https://github.com/jib/ipc-cmd/blob/ecf96f1f73ecc340bb2ff211b70a435ab52e003b/lib/IPC/Cmd.pm#L464-L521

Unfortunately it's not documented, so the only way is copy-paste. IPC::Cmd is in core_perl so it's well-tested everywhere including Windows, so it's a good place to borrow code from. And we'll get graceful killing for free.

The patch by @twata1 is the poor man's version of it (uses the same approach).

I'll upload a TRIAL release on CPAN using my handle and test reverse dependencies or Proc::Guard with it. Then I can take maintenance of this package (my pause handle is NML)

from proc-guard.
