13fd270405 1. Always call user callback function in newly created thread, it seems 
POSIX implies that the user callback function must be executed in clean
environment.
2. Use newly introduced pthread stubs in libc.

e586a0042e Add some more pthread stubs so that librt can use them. 
The thread jump table has been resorted, so you need to
keep libc, libpthread, and libthr in sync.

8e36ba772a Use a thread pool to process notification if sigev_notify_attributes 
is default and caller does not require dedicated thread. timer needs
a dedicated thread to maintain overrun count correctly in notification
context. mqueue and aio can use thread pool to do notification
concurrently, the thread pool has lifecycle control, some threads will
exit if they have idled for a while.

f2e35917b9 The uma_zone data structure defines the size of its uz_cpu[] array as 1, 
but then sizes the containing data structure at run-time to make room
for per-cpu cache data.  Modify libmemstat to separately allocate a
buffer to hold per-cpu cache data, sized based on the run-time mp_maxid
variable when using libkvm to access UMA data.  This avoids reading
invalid cache data from beyond the end of the uma_zone data structure
on the stack, which can result in invalid statistics and/or reads from
invalid kernel addresses.

c1cbeeaeb1 When reporting an error reading from UMA per-cpu cache pointers using KVM, 
return a KVM error rather than an out of memory error, so that the caller
reports the KVM error state.  This replaces a misleading error message
with a more accurate although equally confusing one.
