texlua running for 8+ hours using 5GB of ram on yum update? (texlive-context-bin bug?)

[Paul Wouters]

My yum update on f18 took about 20 minutes installing 3380 packages.

   Cleanup    : bash-4.2.39-1.fc18.x86_64 3377/3380
   Cleanup    : nss-softokn-freebl-3.14-5.fc18 3378/3380
   Cleanup    : glibc-2.16-24.fc18 3379/3380
   Cleanup    : tzdata-2012i-1.fc18.noarch 3380/3380

And then it just sat there and sat there......

What is this? The man page hints of pdf generations. Why is this
happening? Why is it taking 8+ hours? Why is it taking 5GB of RES RAM?

These are several bugs that should be addressed. Endusers will not wait
8+ hours, so right now whoever owns this can be sure it will just get
killed by impatient people. Some people won't have 5GB for this.
