Currently, DXT uses a default of 4 MiB per process for tracing data. We should make this configurable via env variable.

This was fixed with merge request !9

You must export the environment variable ENABLE_DXT_IO_TRACE_MEM to enable DXT tracing. No value will allocate the default amount of trace memory per process (currently 4 MiB):

export ENABLE_DXT_IO_TRACE_MEM=

Assign a value to set the amount of trace memory to use:

export ENABLE_DXT_IO_TRACE_MEM=8 (allocates 8 MiB)

NOTE: The environment variable to enable DXT has been changed in commit 8821f33d to: DXT_ENABLE_IO_TRACE
