Nope. I need to strip out all the nulls from the packet, or any posix
regex parser will think the string ends at the first null. (so protocols
which use null's will be difficult/impossible to identify)
I could modify the regexec function to take a length, but then it
wouldn't be the posix regexec prototype and I was hopeing someone would
add those to the common library of kernel functions, so others could use
them. (and hence make it easier to maintain.)
