Precisely, a usleep(50000) would be much better .  And some man page studying 
for rpmbuild options.  I tried to edit the .c source, but then it refused to 
build and that was not the error it spit out.  We'll poke at it some more 
tomorrow unless I start plowing thru the sources I have for sc6551.asm to 
make that driver, for an H63C09 equipt trs-80 Color Computer 3, now running 

Specifically, I need rpmbuild to stop after unpacking and patching the 
tarball, giving me a chance to edit the .c file to change that, and then 
restart at the next step.  I've been through the man page a couple of times, 
and how to do that hasn't exactly reached up and slapped me.  Hints welcome 
of course.

Thanks Rod.

Cheers, Gene
