Thanks for the answer.
Actually I haven’t enough time but will try to do some thing on my private time
or in few months.
If I find something interesting, I’ll take you aware of it.

libapr1 has been compiled without thread support for a long time, from
before I inherited the package.
I tried enabling it the last time I spun a release. It built fine, but
some of the tests failed. Most importantly, building subversion against
it produced an unusable subversion executable. Apparently, the build
process for subversion detects a threaded libapr1 and does some
different things, and these completely break subversion on Cygwin.
Frankly, I don't have the time or the knowledge to debug the threading
in libapr1. You can try to enable it if you want to experiment. As I
recall, it requires a pretty simple patch to configure.in, although I
don't have it anymore.
I'd be happy to take any patches you create to get threading in libapr1
working.
