 >Description:
 find(1) utility opens current directory dotfd = open(".", O_RDONLY, 0)
 and use obtained dotfd handle later in fchdir(). 
 If current directory is not readable by user then find fails.
 
 >How-To-Repeat:
 mkdir dir
 chmod -r dir
 cd dir
 find /tmp
 find: .: Permission denied
 
 >Fix:
 dotfd handle is only used when -exec predicate is requested.
 find(1) from GNU findutils combat this situation by using getcwd()
 call in case cwd is not readable.
