With Merlin b58, -server flag, VTEST hang on jtgb4u2b1 (Solaris 2.6, Sparc)
after 3.5 hours.
logs files are under /net/jtgb4u4c.eng/export/sail10/bigapps_log/solaris/merlin_b58_server

Coleen Phillimore'e evaluation:
This is a strange hang with not much going on in the system. With the bug,
attach the stack dump (attached). I don't think anyone's going to be
able to tell what's going on since nothing is, but I guess it's worth having
a bugid for it.
