Assert error in SES_Delete()

[Janis Putrams]

Hi!
Running today's trunk. Got this:

Child said (2, 29744): <<Child starts
managed to mmap 536870912 bytes of 536870912
Ready
CLI ready
>>
Child said (2, 29744): <<Assert error in SES_Delete(), cache_session.c line 
344:
  Condition(!isnan(sp->t_end)) not true.
  errno = 0 (Success)
>>
Cache child died pid=29744 status=0x6
Clean child
Child cleaned

Hope it helps.
