in thread Perl threads - parallel run not working

Surely File::find would be unsafe due to shared OS interaction (perhaps a shared stat buf (for "-f _" etc) or shared dir read buffer - I'm speculating here rather than looking at the perl src), rather than whether it uses lexical or package vars (both of which are private to each thread)?

    You are probably right; you usually are.

    I tried File::FInd from threads once about 7 or 8 years ago and found it to not be thread-safe. I took a brief scan inside, found it to be incredibly complex and decided that given its reliance upon global variables and other similar stuff that it wasn't worth the effort to look any further. I've never used or looked at it since.

      Thanks Dave and BrowserUk for your insights.
      Will update if I get some progress on this soon
