100% cpu usage

[wedens]

after some update (i dont know which exactly) unite started use 100% when called second time.
on first run after vim startup it works fine, but second run freezes vim with 100% cpu usage.
vim version: 7.4;
unite latest revision;
unite settings:

if executable('ag')
  let g:unite_source_grep_command = 'ag'
  let g:unite_source_grep_default_opts = '--nogroup --nocolor --column'
  let g:unite_source_grep_recursive_opt = ''
  let g:unite_source_rec_async_command= 'ag --nocolor --nogroup -g ""'
endif
let g:unite_force_overwrite_statusline = 0
let g:unite_source_history_yank_enable = 1
call unite#filters#sorter_default#use(['sorter_rank'])
call unite#custom_source('file_rec/async',
      \ 'ignore_pattern', join([
      \ '\.git/',
      \ 'target/',
      \ '\.idea/',
      \ '\.idea_modules/',
      \ ], '\|'))
call unite#filters#matcher_default#use(['matcher_fuzzy'])
let g:unite_source_file_rec_max_cache_files = 0
let g:unite_source_mru_update_interval = 300
let g:unite_source_file_mru_limit = 20
let g:unite_kind_file_vertical_preview=1
autocmd FileType unite call s:unite_my_settings()
function! s:unite_my_settings()
  nnoremap <silent><buffer><expr> s     unite#do_action('vsplit')
  nnoremap <silent><buffer><expr> p
        \ empty(filter(range(1, winnr('$')),
        \ 'getwinvar(v:val, "&previewwindow") != 0')) ?
        \ unite#do_action('preview') : ":\<C-u>pclose!\<CR>"
endfunction

looks like it's not freezing anymore after removing ~/.unite. i'll close the issue if it will not reproduce?

OK.

I'm experiencing this too. I upgraded to the latest MacVim, unite, and vimproc. After using unite for file_rec/async two-ish times, the whole editor freezes for 3 or 4 seconds at 100% CPU.
