David and all,
Thanks for all of the good work here!
There has been a grwoing question of which threading package will be
made 'default' for 5.x. The main requirement is that the default
threading package be supported on all Tier-1 platforms. Right now,
only libc_r meets that requirement. Here's a quick table from
memory, please correct me if I'm wrong:
i386 alpha sparc64 ia64
c_r X X X X
kse X X
thr X X X
Don't forget that amd64 is up-and-coming also.
Scott
