    BUG/MINOR: threads: fix the process range of thread masks
    
    Commit 421f02e ("MINOR: threads: add a MAX_THREADS define instead of
    LONGBITS") used a MAX_THREADS macros to fix threads limits. However,
    one change was wrong as it affected the upper bound of the process
    loop when setting threads masks. No backport is needed.
    
    (cherry picked from commit bbcf2b9e0d17d83609ac529a21a258d2f2ea7bb8)
    [wt: this should be backported to 1.8 as well]
