Thanks for the patch, maybe we must setup a repository where we  
collect the patches. Because there is lately no response when people  
submit patches for maui.

I also reported that maui crashed when i lot of jobs where submitted  
and i promise that it will be fixed,  see thread:
  *  	[Mauiusers] maui crashes with segv (version 3.2.6.p16) (2006)

and i added some explanation (also from the thread):
I have adjusted the MAX_MHBUF parameter in msched.h to a higher value.
No it did not crash, but it is still possible not to find a free job
hash table slot.  IF you allow more jobs then to have also increase this

/* HvB */
#define MAX_MHBUF           768
#define MAX_MHBUF          4000
