Comment(by pgf):

 that half-second DCON switch is a B2 issue.
 is there a C2 machine on its way to you?  DCON freeze/unfreeze was
 problematic on B2, due to the choice of a surprisingly restricted
 (unusable) interrupt input.

 #  time chvt 1

 real    0m0.036s
 user    0m0.000s
 sys     0m0.000s

 #  time chvt 3

 real    0m0.036s
 user    0m0.000s
 sys     0m0.000s

 #  time (chvt 1 && chvt 3)   [ this isn't always reliable -- i.e., it
 doesn't always switch back.  :-/  ]

 real    0m0.054s
 user    0m0.000s
 sys     0m0.010s

 #  time ((echo 1 > freeze) && (chvt 1 && chvt 3) && (echo 0 > freeze))

 real    0m0.072s
 user    0m0.000s
 sys     0m0.020s
