I'm just thinking of the case where the executive happens to get a segfault, or 
someone kills it, or whatever.  Ideally we would be able to reconnect.  One way 
that I've done that in the past is to mmap() a file in the filesystem and store 
all state information there with checks as to whether its consistant or not.  On 
restart, I read the data in and if it is consistant I just start where I left off.

SA_ERR_SYSTEM.  I suspect its from the poll() timeout in saPollRetry().
