[libvirt] Sleeping 50 microseconds in qemuDomainWaitForMigrationComplete?

There is this nanosleep call in the QEMU driver. /* Poll every 50ms for progress & to allow cancellation */ struct timespec ts = { .tv_sec = 0, .tv_nsec = 50 * 1000ull }; [...] nanosleep(&ts, NULL); The comment says 50ms (assuming m is for milli and not for micro. because normally u is used for micro) but the actual nanosleep call is done with 50 microseconds. Is the comment right and the code wrong? I assume so, because 50 microseconds is pretty short and 50 milliseconds sounds more reasonable. Matthias
