I should mention that the 2.4 patch is old WRT mainline epoll in 2.6 (I 
stopped maintaining it when 2.6 went "stable"). I'd definitely suggest to 
use 2.6 if you are looking at epoll.
I am using linux-2.6.11 and glibc-2.3.4 .. and using select() in it's place seems to work fine. Are there any known issues with say, one thread does epoll_wait()s while other threads may be doing epoll_ctl()s?
There is no known problem in using epoll_ctl() in one thread while another 
does epoll_wait().
I suggest you to ask Valgrind to take a look at you binary. Since I have 
no clue of what your software does, please create the *minimal* code 
snippet that exploit the eventual problem, and post it.
