bugs

[GoogleCodeExporter]

1.there are bugs In Kfs_fuse_main.cc 
2.when client call write(nfd,buf,nwrite) function to write data into dfs,
why the return size is even bigger than nwrite size .Lt is absurd. l print the 
log
and find that it returns the total size that have been written to dfs.
cause l call {int res=write(nfd,buf,4096)} for serval times.
and res is 4096,8192...
l thought maybe it is because of the default buffer in client.
so l call function SetIoBufferSize(nfd,0),but it doesn't work.
what a fun it is .the write function returns some size bigger than 4096,and the 
file is even closed in client,but the file size in dfs is still 4096 big.

so many bugs in the project
