It may not become bottleneck.
1 FD consumes 160 byte in 64bit system. See linux manual at "epoll".
That limit is about max_user_watches, not the general cost of an
fd. Afair they take up a a good more than that.
OH! It's my mistake... I retry to read about FD in linux manual at "proc".
It seems that a process having FD can see in /proc/[pid]/fd/.
And it seems symbolic link and consume 64byte memory per FD.
