flow/manager: (u)sleep slightly longer

Sleep 250 microseconds instead of 100 as running in KVM cause the
old value to use 100% CPU for these threads.

Perf testing suggests no measurable impact for the non-KVM case.

Ticket: #4096
(cherry picked from commit 17a38f1823adeb9eb059f666686e35509f3a13d2)
