Yup. Here's the thread stack at the time the connection was created:
!connect+0x53
!cygwin_internal+0x2b0d5
!setlogmask+0xce8
!setlogmask+0xdff
!aclcheck+0x11836
!sasl_log+0x123
!sasl_get_plugin+0xa6
!sasl_load_plugins+0x2e3
!sasl_client_init+0xdf
!svn_ra_svn__sasl_init+0x9c
!svn_atomic__init_once+0x49
!svn_ra_svn__sasl_init+0x22
!svn_ra_print_modules+0x5d
The sasl_log thing caused me to check /var/log/messages. Here's what
I found:
Mar 26 15:53:28 localhost unable: to dlopen /usr/lib/sasl2/cygdigestmd5-2.dll:
No such file or directory
Mar 26 15:53:28 localhost unable: to dlopen /usr/lib/sasl2/cygotp-2.dll: No
such file or directory
Which is weird, because those DLLs are there. So, next I tried an
strace. I noticed that the /usr/lib/sasl2/*.la files were being
opened, which also seemed weird.
So I tried uninstalling libsasl2-devel. It worked! No hang! This
seems to be the key. The sasl2 initialization appears to hang if the
-devel package is installed, otherwise it works fine.

Works fine for me on all machines without libsasl2-devel. BTW, it
appears Matthias also had the -devel package installed, because his
strace also shows attempts to open the .la files in /usr/lib/sasl2.
