Have same problem. Opera Next is calling clock_get_time() , a function which doesn't exist.
That's a system call.. It seems to be causing the kernel to grow until it runs out of ram.
I think there's a inter-process comm port involved which may explain the memory leak.
I am not sure why Opera needs to call this function so much though - it should call be once a second at the max.
it seems to be making thousands of calls a second - not well behaved.

Isn't it the same or similar problem as the clock issue on WinXP?

May be this syscall is present in previous Mac OS X versions...

10.7.3 kernel version (from uname -v):

kern.version: Darwin Kernel Version 11.3.0: Thu Jan 12 18:47:41 PST 2012; root:xnu-1699.24.23~1/RELEASE_X86_64



The man page for this kernel exists: http://www.opensource.apple.com/source/xnu/xnu-1699.24.23/osfmk/man/clock_get_time.html

but there's talks about how to release this function such this: http://stackoverflow.com/questions/5167269/clock-gettime-alternative-in-mac-os-x
