Comment 2 Jvrn Reder 2002-10-07 00:22:19 UTC 
Setting the environment variable PERLIO=stdio workarounds the problem. So
obviously only the RH 8.0 perlio layer is broken regardings non-blocking I/O,
the stdio layer works fine.

sorry for the weird attachment. those strange charakters are of course tabs...
Comment 4 baulv 2002-10-27 15:24:38 UTC 
I get the same results with RH8.0 and transcode 0.6.1 and dvd:rip 
> 0.47.05 or 0.46. (tested 2 different "cripted" dvd's)
BTW: all the guys using RH 8.0 should urge RedHat to fix this bug. It's
in their bugzilla but without any official reply yet, it's not even 
assigned (still status NEW).
Comment 5 Michel Alexandre Salim 2002-11-05 21:23:12 UTC 
Well it is assigned now at least. Chip, any idea when we can expect at least a
trial replacement RPM? Would not mind testing it... hmm, there's no new version
in Rawhide yet either.
Comment 6 Chip Turner 2002-11-06 16:36:02 UTC 
This bug has been submitted upstream to the perl5-porters list with a revised
test script.  Hopefully something will be heard soon.

Make :unix layer under :perlio not treat EAGAIN as error

I propose this will be applied to perl5.8.1 - verification 
that it solves the original report requested.
