timeout for aio is limited

I set timeout=300 and norandommap.

But actually runtime is limited by runt=138237msec.

Why does it happen? How to work around it?

$ cat aio_time

[global]

directory=/mnt/stp/test

timeout=300

[largeio]

description="large aio thread"

exitall

nrfiles=4

iodepth=64

direct=1

end_fsync=1

ioengine=libaio

rw=randrw

randrepeat=1

norandommap

rwmixread=75

size=2400m

bs=64k

invalidate=1

write_bw_log

write_lat_log

Runtime was limited by runt= 69440msec

When I have used nrfiles=16; size=1200m
