Description dje 2015-02-12 01:04:02 UTC 
I was profiling gdb trying to see why "break (anonymous namespace):foo" was slow.
The problem turned out to be due to a couple of reasons.

One of them is that this program is big.
Big as in "nm $binary | wc" shows ~4M symbols.

Currently MINIMAL_SYMBOL_HASH_SIZE is the constant 2039.

This value needs to scale.
