commit 6d077bbfd3230959846621bbfb1447410e17dd8c

    wilcoxon: Drop now-unnecessary timer support.
    
    Calculating the Wilcoxon significance level now takes only a
    fraction of a second, so there is no need to support a timer.
    
    Also, report the problem if the significance level cannot be
    calculated.

commit e00c8b2ca5092c6871c0cae67be95a884b5671a3

    Speed up Wilcoxon matched-pairs signed-ranks significance routine.
    
    The performance of this routine was O(2**N).  This improves it to
    O(N*W).  For N=30, W=120 this reduces calculation time from 6m9s
    to .002s, which is a 123000x speedup.
    
    Refer to bug #25466 for more information.
