[Xymon] df hanging will cause xymon-client to hang.

[Andrey Chervonets]

I suppose the workaround for the problem can be - rewrite shell script 
calling df.
1) call  df ... command  a) in background   b) redirecting output to some 
temp-file  c) saving child process PID to variable

2) checking in loop the process still running
        if still running (can check with ps command)
        then sleep for 1 sec. or so and go to next check iteration
        if not running - exit loop and check the output
        if count of checks (iterations) more then N (defined in 
configuration), then end checking - raise the red status for disk

3) df is called twice  - for space and for inodes - then implement it as 
shell function
