zcompiling doesn't improve execution speed of functions. It can
benefit you only if parsing takes a long time. Given the small size of
file `taskwarrior` (3.5KB), parsing should be almost instantaneous (at
most 1ms), so the speedup from zcompiling won't be noticeable.

Looks like taskwarrior.zwc is corrupted. My practical advice is to
simply remove this file and not waste time on zcompile as it won't
help you anyway. Slow shell startup is likely caused by the slow
execution of _chpwd_set_task_context. You'll need to either avoid
invoking this function or make it run faster.
