Attach a CoQueue to each in-flight operation so if we need to wait for
any we can use it to wait instead of just blindly yielding and hoping
for some operation to wake us.
A later patch will use this infrastructure to allow requests accessing
the same area of the virtual disk to specifically wait for each other.
