Guess #1 is correct.  The install-tl script warns that this is the case 
when it is run under cygwin.  The updated documentation for TL2009 will 
probably give a similar warning.  But installing the binaries while 
running tlmgr under a different system does not produce any warning.

I'm the person who built the cygwin binaries and made the decision that 
TL2009 should only support cygwin-1.7.  I had a variety of reasons, 
which we could discuss elsewhere if you want.  Angelo Graziosi has built 
cygwin binaries under 1.5, and I'm sure he would make them available to 
you if you don't want to upgrade your cygwin installation.  (But cygwin 
1.7 is actually very stable in spite of being labeled as "beta", and it 
offers many improvements over 1.5.  Moreover, it is expected to go live 
very soon.)
