You don't need anything in your kernel, this is for Qemu network layer

@Serge,
I saw that. It doesn't happen when i extract source on local box via *.dsc
file and build with 64-bit glibc.
I would guess it was attempt to compile with 32-bit version of glibc. 32-bit
support on spice.v35 was dropped.

This patch speeds up coroutine creation by reusing freed coroutines.
When a coroutine terminates it is placed in the pool instead of having
its resources freed. The next time a coroutine is created it can be
taken straight from the pool and requires no initialization.
Performance results on an

Sometimes duplicate code paths are even added, one synchronous and the

Add a microbenchmark for coroutine create, enter, and return (aka

create many coroutines, one per I/O request for example, and we
