Issue #745 has been updated by tuxillo.
Category changed from Other to Unverifiable
Status changed from In Progress to Feedback
Target version changed from 3.8.0 to Unverifiable
Hi,
Moving to Unverifiable because:
- Many VM related work done to x64 at least.
- vfork/exec work was done by Matt in the end of 2013.
- We don't do pkgsrc bulkbuilds anymore but we do poudriere builds which are very fork-heavy and as far as I know this issue hasn't showed up.
Feel free to resurrect/provide feedback.
Cheers,
Antonio Huete

hey,
while doing the pkgsrc bulk build, I get weird numbers in top. I am pretty sure this has something to do with the multitude of shell scripts being used as wrappers in pkgsrc. command execution is also slower than I'd expect (for example wrapper execution).
