I think most of us would consider that an eclipse bug, but yeah, until it's fixed it'd make sense to work around it.
Kinda similarly, I have a mostly identical setup on several machines, and on one of them Firefox has a memory leak, which even showed up just recently. It also seems to manifest if I have certain pages open, the most noticeable of which is Reddit.
It's the kind of stuff I could dig into, buuut it's just a PITA.
I've heard of the year of Linux on the desktop, but I've never really heard of the year of BSD on the desktop. Apart from OSX, maybe.
I guess this is the kind of stuff POSIX could've helped with, but it seems to be busy mandating buggy behaviour.
