Comment 24 for bug 1757517

on my Gentoo/x86_64 system with about 2000 packages installed that covers quite a range of categories of software, here's my stats (using scanelf to count non-symlinked ELFs in various dirs):

$ scanelf -yBRF '%F' /bin/ /sbin/ /usr/bin/ /usr/sbin/ | wc -l
3596
$ scanelf -yBRF '%F' {/usr,}/lib64/ | grep -v -e '\.ko$' -e '/debug/' | wc -l
7806

of those ELFs, 297 have TLS regions. although i've got quite a number of cross-compilers installed, so if i filter out all the gcc libraries (since they're more or less just double counting), i get 85 ELFs.

of those, all but 2 are all easily under 0x100. the only ones over are libpixman which is 0x180, and then x11vnc/libvncserver which is 0x28a0. in this last case, it's almost entirely made up of a structure declaring the vnc color palette. and i don't think libvncserver really needs many threads ... seems to launch short lived threads on the fly for processing input/output requests. i doubt it'll be a problem for these at all.
