Re: Philip, is issue #1556 easy for you?

Not to appear too naive about these things, but shouldn't there be a point at
which XXXX number of locks translates to a single lock on the entire working
copy or the repository, or what not?

To make an analogy, on a RDMBS, if I ask for a large number of things, if my
settings on the RDBMS are correct, a table wide lock is issued and performance
does not degrade. But if the settings are wrong, and each row is locked
indiscriminately, performance degrades as a function of N, sometimes O(N), at
others O(2N) and I've even seen it as O(N^1.5) or as bad as O(N^2).

I don't know if it's specifically applicable to your problem. Just hoping it
might be helpful to think about.
