Actually I think that the bitfield might be necessary. I used it because I 
didn't want to mask out the uninteresting bits of condition flags on lines like 
the the following:

ctx->fds[fd].mode |= condition;

Without either the bitfield or some masking it is possible that this will set 
some higher bits on. If it happens then the parts of code that compare the mode 
against zero will break.

Is it not possible for some higher bit to be set? Can the code stay as it is?
