 recovery-small : @@@@@@ FAIL: remove sub-test dirs failed 

It can't remove dirs because import after evicting is still invalid:

00000100:00000200:0.0:1385996752.852317:0:1047:0:(client.c:1170:ptlrpc_import_delay_req()) @@@ IMP_INVALID  req@ffff880051dd9b80 x1453320200794608/t0(0) o101->lustre-MDT0000-mdc-ffff88005d78ac00@10.3.0.65@tcp:12/10 lens 552/1016 e 0 to 0 dl 0 ref 2 fl Rpc:/0/ffffffff rc 0/-1

Test should wait for import state FULL before remove sub-test dirs.
Decrement of export number may be caused by net issues.
In suggested patch test passes only when import state becomes EVICTED.
