Where did the /proc directory go in Mountain Lion?

I used to find the location of cached flash videos by lsof | grep Flash, the result is something like this Google 38571 lamnk 74u REG 1,2 156826302 37061768 /Users/lamnk/Library/Application Support/Google/Chrome/Default/Pepper Data/Shockwave Flash/.com.google.Chrome.KNc63e Pepper flash player deleted the files so you can not see or copy them, but the process 38571 still hold the files open. Normally I can save the cached flash video by copying /proc/38571/fd/74 to another location. However on Mountain Lion I find out that /proc is not there anymore! Is it possible to get another process to use these file handles and read the files that exist but lack a proper filesystem handle / inode structure? Do I need to configure /proc in 10.8 if the native tools won't work?
