Seriously... We don't need random numbers here, just unique ones. Here's my
proposed replacement, which is also a helluva lot faster than any known good
random number generator:
UT_uint32 UT_newNumber ()
{
static UT_uint32 theNum = 0;
//MUTEX_PROTECT this variable someday soon
return theNum++;
}
Anyone opposed to me checking this into ut_math?
