Johannes Schindelin d00f799d2e Regex: special-case a(a*?)(a?)(a??)(a+)(a*)a

Among other challenges, this regular expression is designed to demonstrate
that thread prioritization is finicky: Given the string 'aaaaaa' to match,
the first four threads will try to grab the second 'a', the third thread
(the one that matched the '(a??)' group) having scheduled the same
instruction pointer to the '(a+)' group that the second -- higher-priority
-- thread will try to advance to only after processing the '(a??)' group's
SPLIT. The second thread must override the third thread in that case,
essentially stopping the latter.
