And that's how it works on Linux, Solaris, NetBSD and probably OpenBSD as well.

Cool, thanks.

You mean what units it uses? Microseconds (at least, in 2.4).

Actually what I meant was what that value is used for in the library.  The phrase "time to live of client connection" confuses me.  Does it really mean "the maximum number of seconds apr_memcache is willing to wait for a single operation?  Or does it mean *both*, implying that a fresh TCP/IP connection is made for every new operation, but will stay alive for only a certain number of seconds.


It is a little disturbing from a module-developer perspective to have the meaning of that parameter change by a factor of 1M between versions.  Would it be better to revert the recent change and instead change the doc to match the current behavior?
