I've experienced a similar effect in Firefox, and though I cannot say
for sure it isn't a GC problem, I notice that it causes a long spike of
intensive I/O, and appears to be correlated with occasional segfaults
and signs of memory corruption / memory leak, and generally happens only
after significant usage over a prolonged timeframe, generally ending up
in a state of extreme memory usage (several GBs in resident set size for
just a small number of persistent tabs) that reset to more reasonable
levels upon restarting and restoring exactly the same tabs.
