Thanks,:]

Not really. I've been thinking about adding support for nonblocking
pipe for similar things but I am always worried about the inherent big
overhead in the execve() and clone() syscalls (especially the former)
and I'm not sure if it's worth the effort.
Maybe the following approach works better for such requirements in
nginx's context:
