| Subject: | MSWin32 improvements |
I've started running some bleadperl smokes on Windows Vista and found
the attached patch useful:
1) It disables all error dialogs from a crashing application so I don't
have to manually close those popups to get the smoke to continue.
2) It lowers the priority of the smoke processes to slightly below
"normal" so that my interactive work on the machine takes precedence.
The first change needs Win32::API and the second one Win32::Process; the
patch simply doesn't apply the changes when those modules are missing in
the Perl used to run the smoke.
