No, this is something no one thought to test.  Thanks for finding it!  
Please report any other problems you find.

Color support will get a little faster soon, and maybe a lot faster later.  
Until then, there are two things you can try to speed it up:

1) Use fewer multi-line regexes.  These can be really slow now.

2) Combine regexes.  For example, instead of saying

color green "\<float\>" "\<char\>" "\<int\>" "\<void\>"
color green "\<static\>" "\<const\>" "\<struct\>"

you could use

color green "\<(float|char|int|void|static|const|struct)\>"

which should be faster.
