Someone over in stable@ list suggested this:

   btw, i turn "debug.mpsafenet=0"
   in /boot/loader.conf to evade the possible network stack deadlock
   under SMP.

in the thread "FreeBSD 5.3 SMP freezes with MySQL 4.1" the last few 
days.

Does this claim of possible network deadlock have any real merit?  If 
so, is it still the case in 5.4-PRE?  If I try the above tunable, am I 
gonna kill some performance?

Thanks.
