I had noticed that on Nov 11, 2003 in src/sys/i386/i386/mp_machdep.c
HTT CPUs are not halted by default.  What is the reason to do it ?
Is it not better to allow logical CPUs to handle interrupts ?

Besides if I try to halting logical CPUs by machdep.hlt_cpus=10 or
machdep.hlt_logical_cpus=1 then computer is partially freezed, i.e
top that running in ssh session could contunue to run but I can not
login to computer anymore.

I'm using 5.1-CURRENT from 2003.11.28.00.00.00 and
machdep.logical_cpus_mask=10
