I will post this here, although it appears to also apply to Thunderbird as well. When running either PortableApps Firefox, and/or Thunderbird on my openSuSE 12.2 Linux machines, I am seeing a very high CPU usage as reported by TOP. Memory seems fine, swap seems fine, and I don't see this issue when running either Firefox or Thunderbird native. I might suspect this is a Wine issue but I do not see other PortableApps using high amounts of the CPU... Thoughts? I see lots of similar problems being reported throughout the internet, but no common thread or solution... What should I do to track this down further?
Here is an example output from TOP -

Cannot say for certain if this is important, but will report it anywise....
I have noticed that often, when I initially start up Portable Firefox, or Thunderbird, the processes seems to consume "normal" i.e. low percentages of the CPU time. But after a while, either one or both will creep up and start to consume high percentages, according to TOP.
I did an strace -p on the corresponding processes, when running normally and when consuming high CPU percentages and got an interesting result.
Normal looks like an endless amount of this -

Internet searches are not turning up much helpful information yet, will keep searching... Any ideas?

Ping? No thoughts anyone?
