[PATCH 0/5] cleanups + posible major fragmentation reduction

[Eric Wong <e@80x24.org>]

1/5 is another attempt to fix sporadic t/imap_searchqp.t failures
This part of Perl still seems mysterious to me :<

Straightfoward stuff:

2,3,4 reduce syscalls and allocations from looking up `git'
(mainly in tests and odd parts this time around)

5/5 appears to be a major reduction in malloc fragmentation in
long-running -httpd and -netd instances under heavy traffic.
I'm still testing, but I'm kicking myself for not trying this
trade-off earlier even though mwrap-perl pointed this out
$ctx->{skel} as a hot spot months ago...

Eric Wong (5):
  treewide: use \*STD(IN|OUT|ERR) consistently
  git: decouple git_version from git_exe
  test_common: use cached git lookup to reduce stat(2)
  treewide: use cached git executable lookup
  www: reduce fragmentation in /t/ and /T/ endpoints
