We have been seeing frequent EAGAIN errors during i/o operations in
tests. This change increases the timeout by 10x to hopefully minimize
these failures.
Per maze@: these methods are dependent on rcu synchronization, which
can take a long time on a busy system. Blocking the thread is
most likely always preferable over failing the operation.
