in thread Debug background Perl procs started with compiled C# code (breaks only on AWS)

Thanks for the suggestion BrowserUK, but unfortunately, the effects are the same... with system 1, ..., the tester proc goes into the background, and when accessed, the ensuing perl process that calls cpanm hangs like it does with Proc::Background.

I've never seen system used with the 1 before. Without it (ie. system $perl ...) it works fine, but the process doesn't go into the background (the system call waits). Where is this documented? Unless I'm missing it, I don't see it in system or exec.

Anyway, I'll keep at this issue for a bit longer, then I'll open an AWS ticket to see if they'll actually help me debug this problem. Perhaps they already know about forking issues...

    Sorry, I'm not sure I've ever seen it documented anywhere. I learned it here 10 o r11 years ago -- probably from Tye -- and used it ever since.
