Nope.
<hansl>
#set verbose off
set messages off
open mroz.gdt --quiet
list X = educ exper age kidsl6
tobit hours const X --quiet

Not related to the original point, but I thought it was worth sharing
anyway: after some summary investigation, it looks as if the warning
you're getting is definitely a false positive due to poor scaling. If you
rescale the dependent variable appropriately (say, divide it by 100), the
warning message disappears. The threshold we use for printing out the
warning message is definitely too strict.
Perhaps we should look into some auto-scaling strategy for truncated
models (internally, the "tobit" command is just a special case of
"intreg").
