Comment (by bgamari):

 Thanks DanielG, this is quite helpful.

 If I compile with profiling enabled the profile claims that heap size
 increases to around 100 MB and then immediately decreases back to
 essentially zero. The GC statistics reported are in line with comment:10:
 {{{
 $ ./LeakyResetStringTable2 +RTS -p -T -hy
 gcdetails_live (MB): 0.9342498779296875
 gcdetails_mem_in_use (MB): 82.0
 VmData (MB): 235.83984375
 }}}
