Some update on Cygwin hangs

[Kelly O'Hair]

Please don't get me wrong.  If the 2 of you decided a 'best course of action' I will always trust your judgement,
my concern was that others did not know you were pursuing this course and I was concerned that we were diverging.

In an earlier email, I mentioned Windows 7 X64 vs. Windows 2003 X64,  if using Windows 7 X64 is a better or more
stable choice, we can abandon Windows 2003 X64.

However, the slower part was due to a bug in configure that didn't detect the number of cores and amount of memory on the system correctly and thus defaulted to running make -j1. I fixed this bug, enabling concurrency for msys, but ran into frequent crashes instead.

We concluded that there seems to be just a single issue left with cygwin: if it hangs, it hangs at the "ctsym bug", so it should be doable to  figure out what goes wrong and work around it. Msys, on the other hand, seemed much more generally unstable.
