The compatibility hooks allows you to use libraries and binaries built and linked to libpthread before libc was built with symbol versioning. The shims can be removed if libpthread is given a version bump.

Add global varible _libkse_debug, debugger uses the varible to identify libpthread. when the varible is written to non-zero by debugger, libpthread will take some special action at context switch time, it will check TMDF_DOTRUNUSER flags, if a thread has the flags set by debugger, it won't be scheduled, when a thread leaves KSE critical region, thread checks the flag, if it was set, the thread relinquish CPU. 2. Add pq_first_debug to select a thread allowd to run by debugger. 3. Some names prefixed with _thr are renamed to _thread prefix. which is allowed to run by debugger.

This includes support for multiple KSEs and KSEGs. The ability to create more than 1 KSE via pthread_setconcurrency() is in the works as well as support for PTHREAD_SCOPE_SYSTEM threads. Those should come shortly. There are still some known issues which davidxu and I are working on, but it'll make it easier for us by committing what we have. This library now passes all of the ACE tests that libc_r passes with the exception of one. It also seems to work OK with KDE including konqueror, kwrite, etc. I haven't been able to get mozilla to run due to lack of java plugin, so I'd be interested to see how it works with that.
